COPYRIGHT INFORMATION: If your quilt was made from a commercial book or pattern, or from a pattern found in a magazine, you MUST also include a copy of the designer's permission for you to sell your quilt.
You cannot profit from someone else's work unless you have his or her permission. When you purchase a pattern, it's understood that you will be making the quilt for your personal use. However, if you are then going to sell the quilt, you will be profiting from the designer's work. You cannot do this unless you have WRITTEN permission from the designer.
I have copied the above information; there is more regarding public domain quilt blocks: specific design elements, color, fabric, scale, measurements ... if you have followed a designer's directions to make the quilt, then you must receive written permission before you sell the quilt. It also states that any small variations or color scheme changes to the pattern do not release you from the copyright ... you will still need the designer's written permission to sell the quilt. Same rules apply to quilts displayed at shows and exhibits. You cannot use a photo of a quilt to create your own quilt and then sell it.
While I have only one page of copyright info., nowhere does it say we can't copy a catalog photo of a kit and keep the resulting quilt for ourselves, nor does it say we cannot give the quilts away ... it only refers to selling quilts. I'm assuming that if I give a quilt to someone, they can't sell it either without the designer's written permission, but I don't know ... it doesn't say.
