I recently made a wall hanging using a picture I had 'captured' on some website...don't even know which one. While I was making it I tried to figure out where I had originally seen it, in hopes that there might be some more information about it. I discovered several similar ones, including one that had been made 'in a class'. None were the one I had found originally however! In addition it appeared that the others used applique to create the celtic knotwork design and I was doing mine as pieced. It is a gift so there's no way copyright should come into the picture. Maybe I could figure out exactly how I did it (trial and error), copyright my method and make lots of $$$.
