Backing

 Now I'm working on backing the strips. I decided to start with the shortest first, the purple, to make sure my technique would work.

 It worked, yay! So then I went to the longest, the blue.

 I'm backing with the color of the strips.

I started the greens, but found an error. I had two blocks with up and down strips together, so I took it apart and fixed it. I decided on a backing fabric, then ran out of steam and stopped for dinner.
