I finished quilting this today. Each row is quilted with figure-8 loops, in colours to match the fabrics. Some strips are all one thread colour; others change 2 or 4 times. I've almost finished hand-stitching the back of the plain black binding, too.
I think I might call it Colour Play, but I'm not sure yet. It's the simplest quilt I've ever made, but I just love the fabrics. I need to come up with more ways of using them without losing the effect of the gradients.
