Once again, I went upstairs, just to put something away, and the sewing room called me. It lured me in and I ended up making several more green churn dash blocks. They do come together quickly.
Here's what they look like next to each other:
I'm not sure if I will alternate red and green or set them in a different way. There are different blues for the centers and different reds and greens for the blocks. Some of the blocks even have different colors in the triangles than in the rectangles. The background remains constant.
I was thinking that for a border I might do two or three long strips of blue and the background fabric and try and mitre the corners. Just thinking about that right now.
