Gosh, there are so many great ideas to choose from! Well, I have jumped in and started the back. I'm using the four patch idea. Kinda sorta. I'm using my remaining black, and for the "second color", I'm piecing stripes. Oh, and I added a couple of vertical stripes. Well, I guess this will be my own variation. I'll post here when it's done! Thank you all for being so willing to help.
