Boy is this a can of worms. I am annoyed seeing traditional blocks being labeled as an "original" pattern at quilt shows and in magazines. How would you ever know who first drew a quilt pattern with squares, triangles, circles, rhombuses, rectangles, etc.? Does just turning a pattern on point make it an original pattern? And how many times have I seen Baby Blocks renamed? There are some new to me patterns like mazes that are truly original and should be given a credit to the designer. But, if I use a patterns from my book of a 500 traditional quilt patterns, turned a bunch around...or not..., would I give the book's author credit? This is a lot to think about and perhaps the "inspired by" suggestion would work. It'd cover a lot of territory. "I was inspired by the traditional quilt pattern Baby Blocks?"
