I always ask that question and what I do is first lay out my squares and then with the ruler lay out how I would cut the fabric. I don't cut yet just envision the cut. Sometimes this enough for me to get a "pucture" of the finished product. The other choice is to just make a sample block. Cut, play with the arrangement of the sub cuts and if you like continue, if not... you get the picture. I made a 30's reproduction d4 and with unbleached muslin as the two opposing blocks and it turned out beautiful. Simple, sweet and perfect for the baby quilt. Sorry no, photo. It is in the camera at home. Any way have fun with the d4 and d9's. Explore and experiment with them. Post your progress. It will be fun for us to see what you choose.
