I don't have a design wall, I have a design bed, which is why Zali the cat loves it so much. I tried to make it so that the bright orange quarter circles were distributed evenly, and the greys, where they meet are all different pattern. I nearly succeeded. There is one spot where there are the same pattern, but I'm not going to tell you where.
This quilt is even too big to lie flat on this bed. That is why I have used a QAYG method and quilted the spirals separately. See my QAYG tutorial here. I think it is a good trade off, as the back is not as perfect as I would like.
