ha ha Marion, join the club! How big is the unsewing project?
I solved a few of these tricky techniques by making small samples and have them pinned to my design wall. Things I don't use all the time like birthing a quilt which I can never remember how to layer or sometimes even what it is called.
Another one is the binding technique where the ends are sewn together. I can never remember which way to flip the ends to sew them.
I Do a lot of machine lettering on bindings and keep a sample of that too 'cause I can never remember the placement even though I do it a lot. Having the samples right there in front of me saves me so much time not having to look them up. When ever I start one of these things I always refresh my memory before I begin. I need all the help I can get.
Put on a great movie or music and sit and relax as you unsew. Call it down time and enjoy.
peace
