When I first began sewing, I never thought twice about purchasing bias tape. At this point, I know how easy it is to make your own. Once you have a few projects under your belt, you have a growing scrap pile, and most of us are always looking for ways to use those scraps. To make 1/2 inch bias tape (as an example) you would cut a strip of cloth two inches wide. Fold the edges (evenly) in close to the center, but not touching, and iron. Then fold the strip in half, folding the raw edges to the inside. That’s all there is to it. The quilting notions area often has small tools to help fold the fabric for you (about $3.50 each, less if you get the store’s coupons), but you are limited to the one or two sizes that these make. This same area of the store also offers small irons designed for making bias tape, but a regular iron works fine. The specialty iron would be most useful to someone who makes their own bias tape on a regular basis.
An advantage to making your own bias tape, aside from cost savings, is the perfect match you can get to your project if you want it to blend in, or the cute patterns you can take advantage of if the bias tape will be an accent to your project.
