This is a variation on my standard go-to for scraps. I made some crumb blocks (stitching scraps together more or less randomly and then trimming square) and created four patches using the crumbs and a solid (i.e. only one fabric) square. Then, I used some strips to border them until they got the size I wanted - in this case, 12", but you could use any size you wanted. I like this sort of effect, because it's scrappy, but at the same time, having some larger pieces incorporated makes it easier on the eye. Also, you can use all sizes and shapes of scraps in a setting like this.
When I made these blocks, I blogged the process; you can see that here.
