A couple of months ago, a speaker at the Guild meeting, was a lawyer and maybe still is, she designs wall hangings. Anyways she gave a talk, that was meant to scare us, I am sure, copying patterns...a no no, except for personal use only. If you sew a quilt and sell it, you are playing against the rules. Now, if I could sew fast enough, I would be tempted to sell a quilt. With everything I do, I can barely get my own sewing done. Not sure how you get around all of it. Good luck.
