I already played some switcheroo but think it's going to stay as it lays!
I purposefully made an all matching paddlewheel, just for fun. I'm glad I added a bit of green to break up the red and blue. There will be a narrow border and then I'll use the same fabric as the setting triangles for a wide border. The finished size is about 53 x 58". See other design walls on Judy's blog.
