I too think that alternating the pinwheel blocks, along the side , top and bottom with plain blocks would take away from some of the busy look, maybe smaller pinwheels. You might also lay a strip of gold fab. in a thin border between the main part of the quilt and the pinwheels to see what that does. That is going to be just precious!!. I think that it would really add to the quilt if you used all white or alternated between white and the purple (if I remember by LSU colors) pararie points around the edges. I used the 3D pinwheels on a wall hanging and added the pararie points, I really liked the effect. You can always just pin some to see what it is going to look like. Check in pictures under my name for some finished work and some work in progress, there is a pic. of the wall hanging
