You may think I am nutsy, but I like to consider myself hardcore....in quilting anyway. I want to share a little problem solving tip that I use when sewing with selvedges.
Sometimes, a friend will give me a selvedge that may be trimmed just shy of enough fabric to add the next one on. So here is what I do....I never throw them out, I just make a new one. Take a narrow strip of fabric, turn under the edge 1/4" and topstitch it to the selvedge . I would use matching thread unlike my little sample in the pic. There you go, ready to use in your project.
