When I posted this earlier, it was just pieces on my design wall. Now I have all the pieces sewn together, and it looks much more like a quilt. The purples still don't photograph "true," but they are close.
It has ended up larger than I thought it would be. I had to turn my design wall sideways and put it on small stools to get this picture. (Hot Rod, my quilt inspector, helped, of course.)
Now I am thinking of borders. The pattern, Ribbon Box quilt..free online... doesn't call for borders, and I may go with that yet. I could bind it in any of the purples. But I really like borders.... I am going to play with the idea of one border in the darkest purple, cut the same size as the ribbons. Who knows if that is what I will end up with. (I will post the finished quilt though, so anyone interested will know.)
