This is why copyright confuses quilters. We all understand if you copy a pattern exactly and don't give credit or try to pass it off as your own that you are infringing. It's when you change the dimensions, make your own version or change it in other ways that is confusing. I think it doesn't matter if it is for personal use or for a gift. If you are displaying it at a show, the designer should be credited. As for selling it, just don't even go there! Your quilt is very eye catching. Good job.
