When I buy a pattern, I am buying the set of instructions and nothing else. That is what the copyright is for. I am in no way obligated to give credit to the pattern designer each time I use the instructions to make a quilt. The designers of quilt patterns are trying to take the copyright laws and make you believe they have way more control than they really do. Think about a pattern you buy to make pants/shirts/ect. Do you wear your pants with a label giving credit to the pattern designer for everyone to see? This is my take on the subject. I refuse to get all bent out of shape because the designer feels entitled to something he isn't.
