This site gives a pattern for "Windmill". If you stack the fabric carefully, with all the motifs directly lined up, and cut them in this manner, you can use "windmill" for sewing. http://www.woodenthimble.com/freepat04.html
If you live in the Rochester NY area, this is a class available. If you are not near there, their photo of a stack and whack quilt is beautiful. http://www.discountsewingcenter.com/class_listing.htm Sara
