I used Quilts, Quilts, Quilts a lot when first starting out and still refer to it now and then. It has photos and patterns in it also and it shows you how to make your quilt block larger or smaller. See if your local public library has it, check it out and see if it is logical for you, then buy it. That goes for other books also. I also have the Better Homes and Gardens book and it's also good.
