Some thoughts:
If I'm going to spend $100 on fabric, I should be willing and able to spend 10 more for the pattern.
If I have a pattern that I've purchased and someone else asks me to copy it and give it to them, I'd be stealing from the original designer.
I'm planning to make a quilt for a raffle held by a not for profit organization. Before I do that, I will ask for permission from the designer. I'm sure I'll receive it, but I'll ask anyway and give credit to the designer on the label.
I have been to copy shops to get extra copies made for a paper pieced quilt and been asked if I have permission to copy the design (of course I do because otherwise I couldn't even make the quilt lol). If the copy shop is so concerned about copyright law, then I'd better think about it too.
