Introduction: Learning from the TRC Collection
The Textile Resource Center is a hands-on collection housed within the Fiber and Material Studies department at the School of the Art Institute of Chicago. It is a collection of textiles from around the world and from different time periods, one that students can pick up, hold, smell, feel, and engage with directly. The rare opportunity this intimate access provides, as well as the needs of students who may be less familiar with textile processes, prompted me to develop a methodology for approaching these objects.
Drawing from key texts in Micro/Macro, particularly Tim Ingold’s writing on lines and Shari Tishman’s Slow Looking, this project developed into a straightforward methodology for examining objects in the TRC, whether individually or as part of the collection as a whole. This methodology is based on the principle of learning directly from the textiles themselves.
No textbook, no lecturer simply telling you what is going on, but a nonhierarchical approach to learning from the object through time, attention, and direct engagement.
Inside the Textile Resource Center
This project was born from an interest in looking at the collection as a whole and considering how seemingly separate objects may be in dialogue with each other. After several attempts at trying to classify and categorize the objects within the TRC in a way that would make sense to future viewers, I landed upon the basic tenets of the Micro/Macro course itself: to look slowly and follow the line. The professor of the class, Isaac Facio, and I agreed that expanding upon the Micro/Macro methodology of looking made the most sense for approaching this collection. Isaac has contributed greatly to this research, and had already formed the basis in the outlines of the class. He went far beyond his requirements as an educator. This was also not without the help and guidance of Delaina Doshi, our T.A., and my classmates, Lydia Mudge, Lee Miko Romero, Lily Burkhalter, Leontine Van Cleef, Erin Sugg, Rivers Zhu, Sitong Yin, as well as Nancy Feldman, the TRC manager. While working on their own individual projects they provided valuable feedback and their willingness to share their firsthand experience of this process is greatly appreciated. This methodology is made with the intention of being a beginning point for those interested in learning from textiles. It is not set in stone in any way, and I hope that there will be changes and improvements made in the future as they are needed.
Why Follow the Line?
My methodology for examining TRC objects, or any textile, is simply one of following the line. Every textile is made up of lines at many different scales and layers. A simple overview of the process involves following single threads of creation as they build into complex structures. Raw fibers become threads, threads become textiles, and textiles are then shaped into new objects. Guided by a human hand, lines create infinite variations in this way.
I have always been amazed and fascinated by the ability of a single piece of thread to form something solid and durable. The TRC gives us a unique opportunity to directly interact with historical objects: feeling them, smelling them, and seeing them in person, allowing us to engage with them in a more intimate way than is usual for historical textiles.

Slow Looking and Key Texts
Two primary texts, along with Isaac's already developed exercises of looking, have formed the foundation of this work. Shari Tishman’s, Slow Looking: The Art and Practice of Learning Through Observation, outlines a framework for learning directly from objects or images/ artwork. While Tishman’s text emphasizes visual learning, she specifically notes that all senses can be used for direct observation. This makes it a good fit for the type of collection we are working with, as well as providing a structured way of learning directly from objects by engagement. Tim Ingold’s text Lines provides an anthropological look at lines, considering their history and roles they’ve played through time. Ingold’s text helped establish the idea of how lines can work in layers, and how layers often depend on each other in communal ways. An embroidered hankie must always be woven into cloth before its surface can be embroidered. Ingold also acknowledges how the word ‘line’ carries many different meanings depending on the context. He includes this list from one of the first English dictionaries below:
“Dr. Samuel Johnson compiled a list of seventeen different meanings of the word ‘line’ for his Dictionary of the English Language of 1755. They are:
Longitudinal extension
A slender string
A thread extended to direct any operations
The string that sustains the angler’s hook
Lineaments, or marks in the hands or face
Delineation, sketch
Contour, outline
As much as is written from one margin to the other; a verse
Rank
Work thrown up; trench
Method, disposition
Extension, limit
Equator, equinoctial circle
Progeny, family, ascending or descending
A line is one tenth of an inch
A letter; as in, I read your lines
Lint or flax
(Ingold 2015, 41)
Four Starting Categories
Approaching lines in layers and how they build up and depend on each other answered a lot of questions about how to consider all of the parts of a textile. This led to deciding on four major types of textiles within the TRC: interlooping, interlacing, intertwining, and entanglement. So far, I have been able to fit all of the textiles I’ve come across in the collection under one of these categories. I’ve defined them as follows:
Interlooping
Lines that move in loops.
Examples: knitting (weft), warp-knitting, crochet, cross-looping, simple looping, most needlework, knots, etc.

Knitting, a structure we commonly encounter in our clothing, is made up of interlocking loops. In conventional hand knitting the line of loops are added in a horizontal (weft-direction) to determine width and increase vertically to create a cloth structure with a single continuous line.
Slip knot
Half-hitch knot

Knots are also formed by looping. Many types of knots exist that perform different functions. Some are made by lines of loops with two or more threads such as macramé, and some are made by one continuous line of thread. Check out Lee Miko Romero’s incredible work with knots for more examples.
Interlacing
Lines that move under and over each other.
Examples: Weaving is made of lines in a perpendicular arrangement; Braids are made of lines in an oblique arrangement (neither parallel nor at a right angle to a specified or implied line; slanting).

Weaving is noted by its perpendicular arrangement, meaning lines always intersect with each other at right angles. Weaving can produce endless amounts of variation, all while based on this simple foundation of perpendicular arrangement.

Braiding is another form of interlacement, but with braiding the angles are oblique, meaning they are neither parallel nor perpendicular. Braiding is used individually to create bands as well as to become components of other textiles.
Intertwining
Lines that twist or link together.
Examples: certain types of bobbin lace, plied threads, certain types of rope, twined baskets, knots, sprang, etc.
intertwining diagram
The most common intertwined example is plied thread. I would argue that most textiles are made up of plied threads. This technique applies a twisting motion, causing separate threads to become one. As you can see in the four-ply cable, already plied threads can be plied again. Multiple layers of plying is how certain types of rope are made.

Bobbin lace is a technique that includes both interlacement and intertwining in its construction. The piece above features a sampler made entirely of an intertwining structure. By following individual thread lines we can see that they link and twist together to create the design.
In the square piece below you can see the different places where thread lines are interlacing and look like small weavings, and where they intertwine to make larger lines.

Bobbin lace is a great example of a technique that blurs between the borders of categorization. There are bobbin laces made only of interlacements, some entirely of intertwining, and many that incorporate both. Lace in general requires a unique approach to classification. Unlike most textile techniques, laces are identified by their significant use of negative space in their design. This means any approach to creating lace is valid as long as the negative space is an important part of the design.
Entangled / Matted / Bonded
Lines or fibers that are arranged irregularly, tangled together, compressed, adhered, or bonded into a surface.
Examples: felt, nonwoven fabrics, paper-like textile structures, bark cloth, and other fibrous webs.

Finding a name for this category of textiles was challenging. I’m still not convinced that it’s the right choice. Originally, I called it “Felting'' as the category name because that is how Irene Emory labeled it. That name doesn’t address the way that lines move to create the variety of textiles in this group, so I’ve been looking for something more accurate. Instead of relying on older names, Isaac encouraged me to create a new one to apply here. The other category names we’ve used above are based on the movements of the thread lines that make them. Following that methodology we can consider how these lines move to create the structure. They’re harder to follow because they are working at a smaller scale, but they are still working in a predictable way. As stated in the examples, these textiles work together by intertangling with each other at a small scale, whether through a process of abrasion as in felt (see below), or cellularly, as in barkcloth. Other names considered were: arbitrary entanglement, intermingled, non-linear, random, interlocked, and interfacing. As with all things in this methodology, this word can and should be changed in the future if someone finds that another term would better describe them.
Felt is created when the scales of wool become locked together through friction. The scales act like hooks that lock together as demonstrated above. This happens on the level of individual fibers. Once they become locked together they cannot be undone. If you’ve ever put your wool sweater in the washer you’ll be familiar with this. The more the lines felt together the denser it becomes. Using this process, scientists have been able to create bulletproof felt.
The definitions might feel basic, but they are the fundamental paths lines take when creating a textile. Some textiles might be able to be listed under several of these categories, for example if a piece is made up of woven fabric and with applied embroidery, it can be listed under interlacing and interlooping respectively. For some it seems unclear where they belong in the first place. If a fabric is woven first and then felted, does it belong in entanglement or interlacement? Or both?
It is my intention that this project should remain adaptable and open to change. Perhaps there are objects I haven’t accounted for that would create new categories, or maybe in the future there is reason to approach the collection in a different way. This remains as a starting point and an aid for those exploring textiles individually and the collection as a whole.
Lines are complex and present in all aspects of textile production. A beginning example of how we can use this methodology to learn from an object follows:
Following the Line in One Object: Scandinavian Overshot Fragment
Scandinavian Overshot Fragment - TRCO 2.79
For this example, we are looking at a piece that the donor says is from Scandinavia. The tag attached says “TRCO 2.79 Scandinavian Overshot Monks Belt Pattern Fragment 1920-1950 weaving wool” That’s the beginning information along with the object itself. It was located inside of the ‘weave’ drawer in the TRC.
Scandinavian Overshot eye level detail
By taking a closer look with our eyes, we can determine that this is a woven textile. The threads that make up the cloth are consistently meeting each other in right angles, moving in straight lines, either going above or below the thread that is perpendicular to them. Woven threads fall under the category of interlacing, one of the four major textile types within the TRC.
If we have good eyesight, or get out a basic magnifying glass to help us, we can take a closer look at the individual yarns themselves.

Looking at the red threads featured in the picture here, we can follow one of them individually and discover that they are actually made of two threads wrapped around each other. So what we previously thought was one single line traveling across the fabric is actually two intertwined around each other and acting as one. At this scale of looking, we can also take a look at how the two different yarns are interacting, by following one of the red lines for example, we see how the design is formed by the changing interlacements of the two types of thread.
If we were to zoom in even further with the help of a microscope we enter an entirely new world made up of lines.

S and Z twist diagram
At this scale we begin to see that the lines we were originally following are actually made up of many lines themselves! Before they are turned into thread, all fibers exist in a raw unprocessed state. For wool, which is what the red thread is made up of, it exists as the wool on a sheep. Just like human hair, the wool has many individual lines of hair. Just like people have different types of hair, sheep have varying types of wool. The behavior of the individual hairs determines a lot about the characteristics a thread will have once it has been spun. In the picture below you can see two different breeds of wool and how different their fibers are.
Comparison of wool from different breeds of sheep. As raw material, these lines are partially arranged due to processing.
These preliminary stages are very important for the future of the thread and the textile they will become. The treatment of these individual lines as they become one unit is another example of small concrete steps building into something brand new.
All textiles come from some sort of raw material. Abi Li, a previous student in the Micro/Macro class, did a research project on bast fiber that provides a wonderful in-depth example of the different layers of lines that exist from the raw state of plant matter through the different stages of transformation as it becomes thread.
How the Methodology Developed
For people following this line of research in the future I thought seeing the process of getting here could be helpful.
When I first began trying to approach the collection as a whole, I tried to categorize the types of objects in the collection. I had wanted to look at the range of techniques and structures represented within the library. At the time I had been personally researching an uncommon type of lace, filet lace, and thought that I might be able to help the library by creating some tutorials for less common techniques featured there. The first step in this seemed to be taking a look at all of the techniques featured in the collection, seeing what existed in the greatest numbers and where similar techniques may be being used in different ways or to different ends.
I quickly realized how enormous of an idea and undertaking it was, not to mention how it would be mostly working on a spreadsheet typing in data. I began to understand the concept of collections management and how these enormous systems may operate in large collections like the Art Institute of Chicago. While this didn’t end up being the project that I continued on to finish, it was an important stepping stone to arrive at this method, even though it seems like a roundabout way now. The TRC online database contains a lot of this information already. Being a continual work in progress means that some pieces are filled out with more information than others. I used a lot of this information as a starting place to get a sense of the collection as a whole.
A snapshot of some of the keywords included in the TRC Database.
Working on the original data started me on considering textiles at the most basic level and how they build up to become structurally and visually complex objects. As I started trying to categorize them I quickly found gray areas and overlapping categories. For example, if I am looking at a quilt block such as TRC Object 6.55
There are many already developed systems of categorization both for textile collections specifically as well as object collections such as entire museums. The Textile Thesaurus is one such system, as well as the Getty Art & Architecture Thesaurus that are both listed in the bibliography. Irene Emory’s book The Primary Structures of Fabrics has been especially influential because of its thoroughness and similar subject matter. The move away from these already existing methodologies is to focus on a system that follows the method of slow looking. While following the line is creating its own path, it is heavily influenced by these extant texts.
TRC Object 6.55 an Amish quilt block
I can definitely classify it as piecework and as part of a quilting tradition. But should I also be paying attention to the woven fabric that it is made up of? It was created with machine plain weave fabric, which is typically what is used for quilting. This means that on a mechanized loom a fabric was created by having threads repeatedly going over and underneath each other. Was the fabric dyed after it was woven? Or maybe before? Either way, the quilt block wouldn’t exist without the woven fabric having been created first. After the woven fabric was created it was cut apart and different pieces of the woven fabric were then stitched back together to create the quilt block we see now.This kind of slow investigation can lead to a wealth of information on an object, but taking the time to do this for every object in the collection, or even 50 of them, expands way beyond the time frame of a semester.
From that point I thought, no, I cannot take a look at every single object in the collection and categorize it.
I started thinking I would just try and make a list of the techniques in the TRC. I moved forward by using the Museum Textile Thesaurus created by the Textile Museum located in Washington D.C. This complex thesaurus includes categorization for just about anything textile that you can think of, from textile techniques, to materials, to uses. At this time I was also told about the Getty Art & Architecture Thesaurus Online, an easy to use tool for considering the hierarchies of techniques and how to classify them. Though it isn’t textile specific, it includes an incredible amount of information and depth on textiles.
A snapshot of the first organized attempt to categorize all of the techniques in the TRC. These resources led to the chart above, a three tiered hierarchy of textile creation processes.
The chart can be read in rows from left to right.
The names entered on the left are the most specific terms and processes. The middle is an intermediary, and the right is the most basic form of construction that the process falls under. For example ‘plain weave’ in column A is a type of ‘Woven’ fabric as seen in column B, and weaving falls under the broadest category of ‘Interlacing’ in column C. It is a hard to read system which is a big part of why it didn’t work out.
This approach ended up being helpful for establishing a basic hierarchy among the processes and beginning to understand the different relationships between them. It had me slowing down even more and considering the close relationships of the things and really following the movement of the line. Were the threads moving in spiraling loops? Or under and over each other repetitively? Did one process always rely on some earlier process in order for it to come to life? This approach, while engaging and insightful, also began turning into a large seemingly unachievable project. (It also taught me how hard it is to make any charts more complicated than a pie chart, and that I don’t know anything about working with spreadsheets.)
Working with Isaac, I decided on some overarching categories for all of the processes, which helped lead to the final methodology of approaching the textile. It ended up being much simpler than all of the above, and brought me full circle to the tenets of the class: looking slowly and following the line.

adrienne maree brown’s Emergent Strategy discusses how complicated structures and systems can emerge from small, repetitive actions. Although the book is usually discussed in the context of social engagement and politics, it became relevant to this project through the relationship between simple repeated gestures and complex textile structures. This connection is especially important when thinking about how fibers, threads, and lines build larger forms.
