I was checking out some patterns I had downloaded and thought I would mention this one.
http://www.3dudesquilting.com/docume...inQuiltPDF.pdf I believe Jenny Doan of the Missouri Star Quilt Company did a tutorial on this but this link also shows you variations of block sizes.
On their website, you can also check out the assortment of free patterns they have listed from various fabric companies, too.
