I'm a beader who is learning techniques from reading publications of various jewelry artisans. Once I learn how to make pieces, I get many requests from people to make similar pieces. I'm wondering if I change the stringing, use different bead types (color, shape, material, etc) or alter bead patterns slightly, would I still be subject to copyright problems, especially if I try to sell finished products? How much detail should I modify in a piece before I'm safe. Where is the fine line between innovation and copyright infringement?
Thanks!
