One of my favorites is cutting rectangles from the fabric, then adding a narrower strip to the two long sides. Next alternate these blocks vertical and horizontal in rows. With those colors, I would probably use the browns and greens for the rectangles and the oranges for the side strips.
If you cut the rectangles 4.5" x 8.5" and the side strips 2.5" x 8.5", your finished block would be 8.5 x 8.5". I am certain this pattern has a name but I don't know what it is. I saw one once and just duplicated it without a pattern. It's fast and easy, but looks great!
