QuiltnLady1 you are right on about copying books and patterns then calling it their own. I took a class on a book called Square Dance when it first came out it had 2 sizes of paper templates that we traced on plastic then another person came out wit the same thing and called it Twister and included plastic templates and doubled the price of the book , never gave the original writer of Square Dance credit for anything. Another one ONE Block wonder a copy of another that I Can't think of the name right now and there are many others so copy right must not work for everyone
