This has been around for a loooong time. I last worked on it in 2015! I still had a lot of strips left (I got rid of the extra squares long ago) and decided to let those go as well. I just did a plain muslin back for the quilt top and zigzag stitched the edges. I will NOT be quilting with this again - the fabric is so thin it stretches and wiggles all over the place, sheds threads, and generally drives me crazy!
