In American Quilter's Retailer Magazine there is a pattern for this that is free for shops to use to teach or make kits or give as handouts. All quilt shop owners should have this magazine so ask. The free pattern is designed for shop owners to use for promotional purposes. Many don't go to the trouble of requesting a free pdf. file of the pattern each time and having a sample made up of the quilt. The pattern is called Woven as One by Susan Fuquay. Here is a great review and picture of the quilt:
