Arkansas Crossroads. There's one version on Bonnie Hunter's site
http://quiltville.blogspot.com/2005/...h-of-july.html with instructions, and you can use any combination of scrappy squares in this quilt as long as your 4 patches have light and dark contrast and you pick one unifying fabric for the larger squares (the ones that are white in the Quiltville version). Do a Google image search for Arkansas Crossroads quilts to see many examples.
