Meet GG, one of the beloved founders of Chicago Canvas & Supply. Although she’s no longer with us, her vast knowledge of industry terminology lives on in this textile dictionary! Each month, we’ll pull from GG’s personal collection of terms—don’t miss out by subscribing to our blog over on the right-hand side of this webpage.
Ready to learn something new? Let’s get started!
GG KNOWS Greige Goods
Greige Goods You’ll probably only hear this textile term (pronounced “gray” goods) by a true fabric connoisseur—it’s almost like a secret code. Greige goods are any unfinished woven or knitted fabric that you’re planning to dye or apply flame retardancy or any other treatment to.
By the way, the word “greige” is so unique, that every time you type it, you’ll get a spell check error. Come on, Webster, get with the program!
GG KNOWS Cheese Cloth
Originally, this loose plain weave cotton fabric (often compared to gauze) was used for pressing cheese. When the 70s came–and you flower children will remember this–cheese cloth started appearing in clothing in a variety of patterns and colors. It’s also a budget-friendly choice for scenery designers in theaters and movies to use for texture and eerie environments. Can you say “cheese cloth”? Take a selfie!
GG KNOWS Cut Size
Cut Size refers to the size of a tarp or fabric before sewing of seams and hems. As an example, for a 6’ x 8’ Cut Size tarp, the material will start at 6’ x 8’. After sewing, it will finish approximately 5’6” x 7’6”. Generally, you will lose 6-9” per dimension depending on the size of the piece and the number of seams needed to fabricate the piece. 3” of fabric is needed to make a hem, plus additional material is needed to sew the panels together.
GG KNOWS Finish Size
Finish Size refers to the size of a tarpaulin or fabric after sewing (hem) has been completed. This means that if the Finish Size is specified when ordering, the extra fabric that is necessary to create hems and seams has already been accounted for and the actual end product will be 6’ x 8’. As such, a 6’ x 8’ Finish Size tarp will finish at 6’ x 8’ after sewing is completed. In other words, the material will start larger, approximately 6’6” x 8’8” and then after the hems and seams are made, the piece will be 6’ x 8’ when completed.
GG KNOWS Cycloramas
Cyclorama (also referred to as a “cyc”) is a large curtain that’s positioned at the back of a theatre stage. Made of canvas, muslin or scrim, cycs are used to create special effects, including the illusion of a sky, open space, and/or distance. First used in 19th century German theaters, cycloramas continue to be used today. Cycs are hung at 0% fullness (flat with no pleats) and, when possible, stretched on the sides and weighted on the bottom to create a flat and even surface for projections or paintings. As seams tend to interrupt the smooth surface of the cyclorama, it is usually constructed from extra-wide material, which makes our fabrics ideal.
GG KNOWS Fabric Weight
You can’t get away from discussions about weight these days–even in terms of your fabric.
Fabric weight describes the mass, or how much a fabric weighs, for a given area or length. Most fabric are referred to as ounces per square yard. As a reminder: a square yard is 3′ x 3′. But you knew that, right?
GG KNOWS Running Yard
A “running yard” is the width of the fabric by every 3 feet. When you purchase fabric, request the width and number of consecutive (running) yards. A typical phrase for vendors of fabric is “price per running yard.” Simple and easy to do your math.
GG KNOWS Monk’s Cloth
Monk’s Cloth is an even basket weave fabric. Monk’s cloth is used in Swedish weaving often called Huck Embroidery. Since this cloth is 100% cotton, it will definitely shrink when washed. WARNING: Be sure to pre shrink fabric before you start your project.
Monk’s Cloth is available in many beautiful colors. You can use yarns and threads to embroider or stitch beautiful images and don’t hesitate to also use Monk’s Cloth to decorate borders on blankets, pillows, clothing and pictures.
GG KNOWS Sharkstooth Scrim
Sharkstooth Scrim is unique mostly to theatres. Sharkstooth scrim allows differed lighting effects depending on front or back light. I have tried to find the origin of this term. A sharkstooth is black and maybe this was the first color this was woven in? I googled all over the place and couldn’t find much. If any of you have more information on why the name sharkstooth, please email me. GG wants to know!
GG KNOWS Colorfast
Colorfast refers to a color that does not shift hues, fade or bleed when exposed to certain conditions. Conditions may be sunlight, washing or rubbing against other surfaces. Be sure to test your fabric choice especially if the fabric is touching another surface. Headache avoided.
GG KNOWS Selvedge Edge
Selvedge Edge is the self edge of any woven fabric. In a perfect world, a “tuck selvedge” is preferred as this is a smooth edge. Some looms create a “fringe” selvedge and has short threads along the edge. Either way, a selvedge edge will not fray. This can be very important depending on your project and can save on sewing time and costs. Only hem a selvedge edge if there is a secondary reason!!!
Muslin is a very handy, dandy fabric. Muslin is a firm, medium to heavy weight plain weave cotton fabric made in a variety of qualities. Muslin is used in the theatre by quilters, painters, crafters and so many more. What’s really exciting is the very, very wide seamless widths available. I would love to see the loom that can weave 33′ seamless muslin. Think of 5 King Size Beds lined up…yikes.
GG KNOWS Grommets
Yes people, those metal holes in your tarp, your curtain, and lots of other items you purchase do have a name. We’ve heard you struggle to explain them every which way but simply said these are Grommets.
Grommets come in sets of 2 pieces – the grommet and the washer. There are choices of finishes such as brass, nickel and black coated brass. There is a universal numbering system and as the number gets higher (#1#2#3, etc) the inside diameter of the center hole increases.
GG KNOWS Commando Cloth
Commando Cloth is constructed just like duvetyn but from a heavier twill fabric. The matte finish and its high opacity make it ideal for blocking light.
A new fabric in the 1930s, this fabric was commonly used for dresses, suits and coats. Than theatres started using this fabric for theatre curtains and the rest is history. Also, Commando Cloth is available in widths of 118″. This is super handy – less seams or no seams. Yeah!
GG KNOWS Duvetyn
First let’s learn to pronounce this tongue twister? Do ve teen. This is a twill fabric with a velvet like nap on 1 side. Usually woven from cotton and flame retardant, this fabric is an affordable solution for blocking light on stages, movie sets, events, run ways and photo studios.
I read that duvetyn was used on the original Star Trek to create galaxies. Glitter was sprinkled on the duvetyn and than cleverly lite. And in Raging Bull Hugh curtains of black duvetyn were hung all around the boxing ring to contain the artificial smoke. So interesting!
GG KNOWS Canvassing
There is a lengthy procedure that we will cover in a separate blog. Most important use the right fabric – a sturdy canvas is the optimum choice. And guess what- many theatre companies repaint these flats several times for different productions.
GG KNOWS Burlap
A coarse fabric made of jute, hemp or cotton and at times called Gunny or Hessian Cloth. German soldiers from the state of Hesse were called Hessians. This coarse fabric became part of their uniform and thus adopted the name Hessian.
This eco-friendly, breathable fabric makes perfect sacks for shipping green tobacco and vegetables. Same fabric, different name, gunny sacks are used for shipping coffee. In World War II burlap was printed with a camouflage pattern and adhered on combat helmets. In the Great Depression, farmers re-purposed this fabric to sew clothing. Not great for long term on the skin! Ouch.
Today, sand bags for both theater and emergency flooding, masks in films, texture on scenery, home decorating, craft projects and in furniture use are just some of burlaps many uses. Chicago Canvas & Supply carries burlap in lots of new qualities, patterns and colors.
GG KNOWS Broadcloth
A lustrous cotton or cotton and polyester, this fabric is used for shirts, blouse and dresses. The smooth, velvety feel makes this an ideal choice for costumes.
Why “broadcloth“? Most shirt fabrics are woven in widths of 29.” Since this cloth is woven in widths exceeding 29″, it was obvious to call it BROADcloth. OK Sherlock.
GG KNOWS Tarpaulins
Going back, tarpaulins were only treated canvas. Now tarpaulins are manufactured from vinyls, polyethylenes and nylons. No matter what the material all tarpaulins are coated to serve as a protection against inclement weather. Most have grommets to allow securing the tarpaulin. Here is something interesting- the hat a sailor often wears in a storm is called a tarpaulin.
GG KNOWS Pile Fabric
When yarns project from the foundation, we have a pile fabric such as velour. A technique of weaving forms a pile or loop on the face of the fabric. Small blades slit the loop which becomes the pile. Brilliant.
GG KNOWS Ducks
Quack, quack, quack. OK I just had to get that out of the way.
Ducks are closely woven materials and are non directional. The family of ducks best know are number ducks, ounce ducks and army duck. What makes each unique are the weights and number of yarns either woven in pairs or individually.
“Number Duck” canvas is ideal for artistic painting and industrial uses. Here is a hint- as the numbers get lower (i.e. #12-10-8) the canvas gets heavier.
GG KNOWS Canvas
Since we named our company Chicago Canvas & Supply, obviously we are very serious about canvas in all forms! Canvas is a cotton fabric with an even weave that comes in various weights. A single filled duck canvas is our go to fabric for dropcloths, tarpaulins and colored canvas.
GG KNOWS Textiles
There is an endless list of textile terms. I once read there were 18,000 textile terms but that was a few decades ago and new ones are constantly popping up! A textile is made of fibers that are woven, knitted or pressed. Other terms often used will be cloth or fabric.
