I played around with the Sandy Dunes block when making the sample quilt layouts illustrated. As you can see, the quilt shown on the left uses a simple straight set with sashing. Changing up the sashing colours produces a visual secondary pattern forming a sort of "staircase" effect in the design.

By adding extra blank blocks to the quilt illustrated on the right with blocks set on point, the focus becomes the pinwheel shapes and gives a different geometric look to that quilt. What can you come up with?
