I am sure you will have answers from folks here...not from me, unfortunately. I always have trouble selecting fabric and patterns. I suspect some sort of scrappy idea might work. Well, wait, here is an idea. Cut 2 1/2 inch strips the width of the fabric, sew 5 together, cut into squares (I think that would be ten inch squares), then alternate the directions of the stripes, putting sashing between them. I did this several times and liked the results. Let me see if I can find any pictures.
