What a great idea to have the pattern on both sides. All the OBW's I've made are meant to be hung on a wall, but if this is a bed quilt or throw, what a wonderful idea. By the way, all of you out there who are trembling with apprehension, making a OBW is (for me at least), the fastest and easiest method to make a quilt. Finding a great fabric is the key. Find a print in the colors you like, the actual pattern doesn't really matter, since it will be cut up in small triangles, it's the colors that are important. Make sure the background is swirls of color, not a solid. I've always turned my triangles different ways and not always had the straight of grain on the outer edges. If you are careful, those bias edges won't give you any grief. I've also used more than one print. This makes the whole arrangement of the blocks a bit stickier, but they do work. My next step is to make an octagon OBW. I also want to make one with all cubes of different sizes.
