Beyond the Quilt in a Day books (which some are very good), I like the Quiltmakers Gift. Really beautiful examples of pretty basic quilts. Shows a lot of how to vary fabrics to achieve a completely different look from the same blocks. Has Irish chains to Around the World to many many more. There are two of those books with about 40 patterns I believe in them. These took my quiltmaking to a new height.
