It's no exaggeration to say I've been working on this wall hanging for 15 years. It's based on a lovely Mary Engelbreit design. I am pleased with the way I've incorporated other materials into it, but my skills were not great when I started. So the edges are uneven, and I don't know how to even them up without losing some of the design. Also, I used yellow chalk to mark where the letters should go, and now it won't rub or wash off. Please help me finish this after so long.
