Okay, first off this is my understanding of copyrighted quilt patterns. Almost all patterns state that they are for personal use. You are free to make that quilt and keep it for yourself, give it away or even enter it into a quilt show. (and of course that means it is perfectly fine to display it on walls) Now here is what Quiltmaker says about the use of their patterns.
"No one may copy, reprint or distribute any of the patterns or material in this magazine for commercial use without permission of Quiltmaker. Templates and patterns may be photocopied as necessary to make quilts for personal use only. Quilts made from any element of a Quiltmaker pattern may be publicly displayed at quilt shows or donated to charity with credit given appropriately."
