I feel like I'm "getting there"! I decided to use the Sashing Stash Fabric the way it was designed to be used, as a short cut to making small units. In this case I used four little squares for the corner-stones. I think I kept it modern by not having them all the same, some have the black on the top left and some on the top right. (It's the little things.)
Right now this measures 30 inches square. I'm going to add a border, then see if it's "done".
May your bobbins always be full,
