Martindale Textiles 101 - What is a Plain Weave?

The plain weave is the foundation of nearly every woven textile. From airy silk organza to rugged cotton canvas, this simple over-one, under-one structure creates some of the most versatile fabrics in the world.

In this guide, I'll explain how to identify a plain weave, why it's ideal for beginner sewists, and how fiber choice dramatically changes the look, feel, and performance of the finished fabric.

Martindale Textiles 101 - What is a Plain Weave?

As I am learning more and more about textiles and the creation of different fabrics, I want to gather my knowledge here, as a way of testing my knowledge and as a way of sharing it with others who are new to textiles.

We shall start with the most basic weave of them all: the plain weave.  If there was One Weave to Rule Them All, this one is it.

Plain Weave

What is a plain weave?

A plain weave is the simplest, most basic type of weave where one weft thread goes over one warp thread and then under one warp thread to create a 1x1 weave.  It is also the most versatile weave, ranging from the sheer and delicate plain weave of silk organza to the rugged cotton canvas.

In what types of projects can I use a plain weave fabric?

Nearly every project you can think of from clothing to interior decor to costume design to crafts can use a plain weave.  Because nearly every type of fiber can be woven in a plain weave, there are endless options in terms of hand and overall look.  A plain weave linen will be have a matte finish (great for table cloths and summer shirts) while a plain weave silk will have a lovely sheen (great for curtains or fancy skirts). 

When you think of a plain weave, think of stability.  If you are looking for a beginner level project where you need a stable fabric that is simple to cut, pick a plain weave.

What level of sewing knowledge is required for a plain weave fabric?

Plain weave is a beginner level fabric in most cases.  A plain weave is the most forgiving fabric for beginners because it 1) has very little stretch, 2) has a visible warp/weft, making pattern alignment much simpler, and 3) is very stable.  

The only cases where plain weaves become more complicated is when the fiber being used is very slippery or has a significant amount of stretch (added elastane), which makes cutting more difficult.

How much stretch does a plain weave fabric typically have?

Because the threads are intertwined one-over, one-under, the resulting fabric will have very little mechanical stretch (unless the fiber has been combined with elastane or another stretch fabric), which means it is very stable and easier to sew with as it will not warp like other fabrics can.

How can I tell if a fabric is a plain weave?

Look at the fabric up close and see if you can find a visible weft (horizontal) thread.  Once you have found it, follow the thread across the fabric and watch it disappear and reappear under the warp threads.  If the threads are creating tiny, regular squares, it is most likely a plain weave.  

Check the stretch.  If you pull on it from one direction and then the other, it should have very little stretch, unless it is blended with elastane or spandex.

If there is an unfinished edge, find a loose thread and pull on it a bit to see how it unravels from the remaining fabric.  A plain weave should make itself pretty clear.

How durable is plain weave fabric?

Durability will depend somewhat on the type of fiber being used as well as the tension used during the weaving process.  A tight, plain weave cotton fabric will be durable and will resist snagging.  A loose, plain weave silk will be less durable because there will be more space between the threads, making it more likely to snag.  However, overall, plain weave fabrics are durable.

What else should I know about plain weave?

The plain weave is the oldest and simplest weave in existence, yet it remains one of the most useful.  Thousands of fabrics share the same woven structure with wildly different and beautiful results and purposes.

Until next time,
