As I was making my new dance bag, I realized how shabby my little string backpack was. It was some freebee from Rob's work years ago that happened to be a really useful size. I've used it a lot over the years. It's faded, dirty and is starting to develop a few holes. Time to replace it!
I dug through my orphaned blocks for inspiration and discovered a handful of blue and green four-patches that I don't even remember putting together. Must have been some experiment that failed to launch. There were enough pieces to make the bag with two four-patches left over. Perfect.
The pieced sides by themselves could easily pull apart so I backed them with some fabric and ran some wavy lines of stitching over them to hold them all together. Then I stitched the sides and the bottom and rolled over a sleeve on top for the string. I bound the inside seams so there were no raw edges.
