Many commercial patterns instruct you to use twill tape or seam binding to stabilize edges. I never seem to have either in my stash, and even when I buy these notions, they rarely come in the right colors for my projects. But there’s an easy, inexpensive alternative:
The selvage of a silk fabric.
In the case illustrated above, I used the selvage from a burnout silk chiffon. The selvage is very tightly woven, and provides stability to the waistline seam of a bias cut top that I’m working on. It’s important that you use the selvage of a tightly woven, stable fabric, like chiffon, organza or charmeuse. Crepe or similar fabrics will have too much stretch to provide the stability you need. But it’s inexpensive, and you can frequently find it sitting right in your stash.
