Like none of us have done the same thing .. Or from a magazine or even a quilt show .. So no worries just acknowledge that its not your design but blah blah blah .. there ya go .. and I think as long as you don't sell it; just make sure you acknowledge the design but blah blah who did it, etc... Then once you make it big; be sure to shop at that LQS and secretly know you are doing good. Pay it forward with a quilt to a homeless shelter or a woman's shelter once you get the pattern down. When I lived on the other side of the mtn, I made small quilts for the local woman's shelter for the kids.
