I saw a quilt picture on a very popular quilt blog this morning. The blogger showed pictures step by step how she made it. It is the same pattern that is in one of the newer quilt books out now. The book was not listed nor was the pattern designer. The blogger had a different name for her quilt. Instructions are not copyrighted so I can use her instructions and make this quilt and display it, sell it, write my own instructions and copy them all I want. What's the difference?
