Linear Foot Image

How much is a linear foot?

Because we offer so many different fabrics, of different widths, the easiest way to order is by specifying how long the piece of fabric will be. We describe the length of the fabric purchased in linear feet. So, for example, if you order 22 linear feet of a material, you will get a piece that is 22 feet long x the width of the material. The width of each material is listed near the end of the product description.
