Missouri Quilts has a cathedral windows video she did a couple years ago. I made a small one to try it out as I'd never made one before. With her instructions you can make the blocks any size you want. I'm now making a queen size bed quilt and boy is that a job in itself. Still trudging along on it but need to get it finished to give to a couple before they leave the area. The smaller one was so much easier. I even took it to the quilt frame and quilted parts of it afterwards. Since I took it to the quilt frame I'm sure I added batting another backing but used muslin since it was just a quilt for me.
