Technically, a square is also a rectangle. And since the rules didn't just require the use of oblongs, you can also incorporate them into your design.
Sorry for the lousy graphics and colors, but this is a pretty easy block, yet, with the right fabrics, can be very interesting. Also, instead of making five 12" blocks (or whatever), you can make each 12" block from 4 of these and get a much more complex look.
It's very forgiving, no seams have to match, and you just have to deal with one partial seam.
I think of it as a great stash buster - if I see one more D9P :roll: :roll: . So if you've got a fabric collection, or even an all scrappy look (light/darks), it's a breeze to work up.
