You know, this is an excellent question. My grandmother told me when I was a little girl ( I loved to sew then too) that I was not supposed to sew on Sunday. That every stitch that I sew on a Sunday I will have to pull out with my teeth when I die! I joke you not! Needless to say, to this very day I still think twice before I sew on Sundays, but every now and then I let my rebellious nature take over and do it anyway. I really don't see anything wrong with it. I was just "conditioned"......LOL!
