One of the simplest is a rail fence...no seams to match and different ways of laying it out to get different looks. you can google "rail Fence quilt" and get lots of info on it. You can make it scrappy by cutting individual pieces, or use the strip piecing method, which is simpler, and get a little more control of colors for the design. If you need addnl help, just ask.
