Girl, just have fun! Don't worry about it so much. I consider the design mine if I thought of the entire process. If I used a pattern or design from another source, I consider it theirs. But, I don't make myself crazy about any of it. I give credit to the first pattern maker or designer whose work I use. Otherwise, I could spend eons trying to figure out how to do it just perfectly. Forget that....I have quilts in my head that need to get out!
