I agree with SueSew. The book even talks about the fact that you will probably not use all your hexagons. You can use them to make potholders, tote bags etc. I like the way it looks now! I'd fill in the two bottom corners and call it done. I square all mine off, so after you sew all the patches together, I'd cut off the excess at the top & bottom. Add a narrow solid or blender border, pulling a color from the fabric. Add a wider border, either using the focus fabric (if you have any left) or another blender. I love OBWs!
