There is one aspect of copyright that I just learned recently, and it concerns me, because I know I am not in compliance. If you make a quilt from a pattern of a copyrighted design, you need to get the pattern maker's permission to display that quilt in a show, or even to display pictures of that quilt. I understand that most pattern makers will readily give permission, but it is an extra step that most of us are not willing to take because it seems so ridiculous to get permission to display what you legally made.
