Strength Layer Fabrics

icon freeMany corsetieres would have you believe that a "real" corset is only made from coutil. It is the official fabric of corsetmaking, designed for that specific purpose.  However, not only are there several reputable contemporary corsetmakers not using coutil, but our recent trip to Symington's corset museum reveals that not a few historic corsets were single layer affairs of plain-weave cotton.

Coutil is generally characterized by its fine, tight herringbone weave, which provides exceptional stability under high tension. Satin and brocade coutils are also available, so the term coutil describes not a particular weave but the intended end use of the fabric. (More about this self-reflexive definition and how it affects you later.)

Coutil itself can be subject to hype and is actually available in different grades of quality. The purpose of this article is not to guide you to one "right answer," but to help you learn to identify the general characteristics that make a fabric well-suited to the demands of corsetmaking.

Advantages of Alternative Strength Fabrics

So why not use coutil anyway? How can you argue with a fabric whose entire purpose is to make beautiful, strong corsets? There are a variety of reasons why a corsetmaker may choose not to use coutil:

  •  A beginner's first corset (or three), or a corset intended only for short term use such as testing a concept, a photoshoot, a party costume, etc, might be considered by the maker to be a waste of the fine fabric.

  •  Depending on where you live, coutil can be quite expensive, at least if you want coutil of a decent quality. Los Angeles based Richard the Thread offers a domestic coutil that is quite affordable, and, as I found out firsthand, quite stretchy, which rather defeated the purpose. English or German coutil can cost an American $30 or $50, or be difficult to source more affordably. While I've heard tales of great coutil scores on Ebay, that type of sourcing can be sporadic and unreliable.
  • You might be constructing a single-layer corset of a particular color or design, and unable to find a coutil that suits. When I worked at a fabric shop in Los Angeles (a high-end jobber, S. Rimmon Imported Fabrics), I found a few small bolts of batik cottons cleanly fused to some very stable canvas. By limiting yourself to coutil, you limit your options as a designer.
  • Or you might have access to fabric jobbers, who buy leftovers from mills and designers. You might find a lovely, soft, tightly woven herringbone cotton - just because there's no label on it saying it's coutil, does that make it less appropriate? This is a problem specific to coutil; you don't find a houndstooth and think, "But is this REALLY a houndstooth or does it just look like one?" You can question where the fabric was milled, you can test the fiber content to confirm that it's wool and not acrylic, but you can see from the weave that it is, in fact, a houndstooth. Personally, I'm not swayed by the prestige factor of buying a fabric that has the label "coutil" on it. This isn't like buying a designer knockoff purse, it's more like the difference between "champagne" and "sparkling wine," except maybe for some reason the alcohol percentage isn't marked on the bottles...
  • Perhaps you just think to yourself, "Nothing against coutil, but there are plenty of other serviceable fabrics available." Duck, drill, and canvas are all frequently used by corsetmakers. One extremely well-known and respected corset house uses a simple high-quality cotton poplin as the base in all their corsets, which allows them great coordination of the lining color to the fashion fabric. That flexibility has the advantage of minimizing the bobbin thread color dilemma.

Personal Ethos

Sample corset with organic cotton sateen fashion fabric.In my case, I am committed to making Pop Antique a line that uses sustainably sourced fabrics. In the end I settled on a domestically-produced organic cotton canvas for the base layer that goes into every single corset. 

A quick blurb about organic cotton: Conventionally grown cotton takes up about 2.5% of cropland... and consumes 16% of pesticides. As far as "dirty crops" go, non-organic cotton is literally the dirtiest.

Since the same strength layer fabric gets used in every corset I produce, I decided it was most important to use a sustainable fabric there, rather than in the constantly-changing fashion fabrics. Using a "special needs" fabric doesn't mean you have to compromise on quality, if you're willing to go through a bit of effort with sourcing.

You may find that it takes a couple samples or so before you really know whether a fabric will work or not, so it may be best to start off purchasing a small yardage before you commit to a bulk order with its associated discount. You're not saving money if the fabric doesn't work out, though you can still keep the less favorable fabrics around for samples and mockups.

 

Sourcing Fabrics

There are several methods for sourcing fabrics, and I wouldn't recommend sticking to just one. What feels like a daunting process the first time around gets easier as you gain familiaritywith it. 

You can order swatches and have them mailed to your home or studio.The first sourcing method most sewers learn is to wander around their local and not-so-local fabric shops or districts. This is dangerous for your pocketbook because you're probably going to see and fall in love with other fabrics, not related to your quest, in the process, so keep your blinders on and stay focused.

You might ask your other designer friends where they get their fabric and hope they're willing to share, though some will consider such hard-earned information confidential.

Or you could ask our good friend Google, who doesn't care about such things, and see what pops up. Some fabric suppliers, both brick-and-mortar and online, will provide swatches for free or for a nominal fee (usually around 50¢ per swatch).

It's sometimes possible to order a swatch kit of a company's entire catalog. If you call or email a company and give them a general idea of what you're looking for, they can pick things out for you, or you can select specific fabrics from an online catalog.

If you're visiting a shop, some don't allow swatches, or have a limit on the number you can take, and you'll have to examine the fabrics while you're there, rather than taking them home or to your studio to ponder extensively.

 

A Short List of Basic Properties

So what qualities do you look for in these fabrics?

You want a fabric that is:

  • strong and stable
  • comfortable against the skin for unlined corsets
  • easy to cut and sew
  • going to add a minimum of bulk at the seams

A Weave's Relationship to Stability

Stability is arguably the most important of these qualities. A big part of a fabric's stability is determined by the weave of the fabric. While denim is often used for beginners' corsets, it's unsuitable for long-term or professional use because denim's twill weave is on a diagonal. I've never used denim to make a corset, but supposedly it twists because of this (I believe it). It is said you can offset this by flipping each panel to alternate diagonals and balance it out. I imagine it's also harder to navigate the grain line on denim, and cutting your fabric off-grain can also lead to twisting. A plain weave or a herringbone both have a weave that is already balanced, so you only have to worry about one grain line and not the nap of the fabric.

Swatch Test 1

 Hold the fabric between your hand like this, and tug.The first thing I do when considering a fabric is to hold it firmly and tug on it to see how far it stretches.

I usually start with about two to three inches of fabric between my hands, then I might try for a bigger piece if I'm looking at yardage and not just a swatch.

Test both grainlines and the bias, just to really get a sense for it. If you can stretch it a fair bit just by tugging with your hands, imagine the force exerted on it when it's compressing the wearer's waist for hours on end each time it's worn.

It helps if you can do this while holding the swatch against a gridded cutting board or something else that will give you a visual measure of the amount of stretch. (As an experiment, you may also try doing this with your twill tape or petersham.)

 

Take a Closer Look

Comparison of two different cotton canvases. Can you see which weave is more suitable?Now, look at the yarns that compose the weave. How far apart are they? How thin or thick is each yarn?

You are aiming for a fine, dense weave, for several reasons. Yarns that are closer together make a stronger fabric, and your stitching will be much cleaner on a finely woven fabric.

A canvas with thick yarns can create a jagged stitching line on the bobbin side as the needle is pushed around each yarn. If you're flipping your corset over while you stitch, then that jagged stitching could end up on the exterior of the corset. Plus, the finer, denser weave will be smoother and softer for the person wearing it.

Think of buying bed linens – though the application is different, it's still a fabric that interacts with your body in a personal way, and the higher thread count equates to luxury and comfort.

A weave that is both dense and fine will provide the necessary stability without contributing undue bulk at the seams, where you're likely to have a minimum of four to six layers of fabric. While stretch, or rather, lack thereof, is the first thing I check for, you can see how weave density impacts a fabric's suitability in at least three unrelated ways.

Fiber Content: Cotton

Typically, you probably want your fiber content to be 100% cotton. I actually quite adore cotton as a multi-purpose fabric. It's very comfortable and easy to sew, dye, and care for. It's also probably the most comfortable fiber against your, or your client's, skin. Some people have very sensitive skin and can experience minor itching or even allergic reactions from certain fibers.

Swatch Test 2

If you're buying fabric from a jobber and are unsure of the fiber content, you can do a simple burn test. Using matches or a lighter, burn a corner of the swatch or a tuft of threads.

  • If it just burns to ash, it's plant-based.
  • If it smells like burning hair, it is a protein (animal) fiber, such as wool or silk.
  • If it melts, then it contains synthetic fibers.

Regarding Hemp

Naturally there are advantages and disadvantages both to using fibers other than cotton. I made a few samples in the spring using hemp canvas. I was quite enthused about the idea of a plant fiber that was seven times stronger than cotton. The canvas felt very sturdy and had little stretch when tugged on the straight-of-grain.

Unfortunately, the hemp canvas I'd found had fairly thick yarns, had to be grown and milled in China, and had a distressing tendency to slide in the direction of my rotary cutter while I was cutting it, which was both annoying and had the side effect of causing the panel to grow slightly vertically. It had a bit of the same slippery quality as a charmeuse or 4-ply. Corsetmaking is finicky enough as it is, so you don't want to make your job harder by using a fabric that is challenging to cut and sew.

Swatch Test 3

All of this leads me to my final swatch test. Holding the swatch between your hands as in the first test, slide your hands parallel to each other but in opposite directions, as if they were trains on parallel tracks with different destinations.

What you're looking for involves both the feeling and the appearance of the fabric. Visually, you are looking for casual bias wrinkles. They are an indicator of stability. Whether you get that sort of stress wrinkle in your final corset or not will depend more on the pattern you use, so it's not a cause for concern.

If instead the swatch glides smoothly in this test, with only a slight, shallow wrinkle, then it's too giving and will be prone to shifting in the construction process.

Though the shifting of the hemp canvas I tried could be managed with pinning, I would not describe it as a particularly efficient use of my time.

Slide your hands in opposite directions. These wrinkles indicate a stable fabric. The rectangular swatch has become an parallelogram with only light phdiagonal stress lines, indicating that it will shift during cutting and sewing.
   

 

Fin

Whether you choose to use coutil or not, I hope this article sharpened your critical thinking skills when it comes to analyzing fabrics, or at least solidified some concepts that you'd already begun to subconsciously observe on your own. If you're comfortable sharing, I would love to read in the comments what your favorite strength fabric is and why, and I'm sure your fellow readers share that sentiment.

  Excellent timing, I just led a panel on intro to corsetmaking last weekend at a conference, and tried to emphasize to the participants that No really, you don't have to special order coutil for your first corset!. I'm not very clear on the final test, though -- it doesn't look like the second picture has any wrinkles at all...

  Some images seem to have gotten missed in the upload, so I've popped them onto imageshack. It's easier to see in person (and I had to hold the swatches funny to take these shots with the self timer), but here are 4 images, before and after of two swatches with different weaves and fiber content. The first is organic cotton canvas, the second is hemp herringbone. It's also something that you can kind of feel, as well as see, while you're doing it.

  Thanks for this article. I especially appreciate the bits about a thick yarn fabric's effect on the bobbin side of stitching. This issue has kept me from attempting a single layer version of a project on more than one occasion.

With regard to alternative fabrics I am fortunate in that I live near a “Fabric Clearing House” sort of place that has a large but inconsistent variety of fabrics for very affordable prices. I have found a material that works well for mock-ups which they've told me is “Sunbrella ”. It is a tightly woven sort of synthetic canvas whose intended application is for outdoor/patio furniture upholstery. I like it because it does not fray at all, it does not stretch at all, it is easy to sew (it's not much thicker than coutil) and in a single layer mimics the form holding/firmness of a three layer finished corset (fashion laminated to coutil with a liner).

  I agree with beautoner above. Though I have not used Sunbrella in place of Coutil (as yet), I have worked with Sunbrella fabric before which actually has a beautiful, smooth feel and is easy to cut and work with. (No fraying either!) Agreed that although a quality canvas holds up well, fraying with serger is a problem.
Thanks for both the article, tips and comments.

  This "sunbrella" sounds quite intriguing, I will definitely have to investigate it sometime.

  Be careful what u use Sunbrella for. Outdoor fabrics are treated w/ chemicals for waterproofing and sunblocks. You might not want this on your skin.

  I've never made a corset before and decided I couldn't because coutil is not available in my country. Thank you for this article as I now realise I can use another fabric.

  Very helpful article, thank you so much for writing it -- and so funny you worked at Rimmons -- that's my favorite fabric store, although it's about an hour drive into LA for me -- well worth it.

  Thank you for such an informative article. I am a noobie on a mission. As per your query regarding fabrics, I have yet to venture that deep and so do not have an opinion. As someone on a limited income and because I like to reuse, I will be buying my fabrics at second hand stores, and you have armed me well for discerning the needs of the fabric for a corset.

  I was taught to use Down Proof Ticking, and I still do, for the most part, though I"ve also experimented with some light canvases, used by themselves for Quick & Dirty start projects, where the goal is to have a wearable garment as quickly and simply as possible, to then refine and make pretty. The ticking is very fine, a tightly tabby / plain woven cotton. Sometimes it is a red and white "shot' fabric, and sometimes it is unbleached cotton. Weights vary by store, but it is a little thinner than a denim shirt, maybe like a heavy chambray, but it's hared to tell or compare, due to the differences in tightness. It is very different from regular or railway ticking, but might also be called Pillow ticking. I probably use 2 layers of it, with bones between the layers, boning channels stitched to all 3 layers, then a light lining put in, only attached at the edges. I hope this helps. Thanks for the confirmation that I am not bad or inadequate or a lazy cheat for not using "real" coutil.
