At the encouragement of my BQB Jan, I tried the Stack 'n Whack method of cutting fabric to make a kaleidoscope effect. But instead of layering 8 pieces, I only layered 4 and just cut squares. It was a good way to get my feet wet and besides, I don't have one of those fancy long triangular rulers anyway.
This is the result.
This is the fabric I started with.
I didn't intend to get this far on it, but once I started, I just kept going and decided this would be a NICU quilt.
