A 4 by 4 isn't always a pick-up truck, to me, it's 4 blocks sewn together. This photo shows that where the 4 corners come together, it makes a secondary pattern. Getting all four colors to be represented throughout the quilt top at that intersection, a bit of a challenge This was one of the easiest quilt tops that I have even sewn together since there aren't that many seams to match up and since the kites are all cut out on the bias this makes them very stretchy.
