Here's the final scrappy block quilt. It measures 34" square.
I did a lot of quilting practice on this piece, but my kitty does not care. She loves her new blankie and has given her approval. I had to snatch it back from her to take the pic.
I had to do some planning and thinking about how I would add the borders and then attach them. I chose to continue with the quilt-as-you-go style and use the thin black sashing strips to connect the outer borders and corners. I was able to use up a bunch of scraps, but I still have a ton to go, so I'll probably make one for my other cat, too.
