The quilt you showed is a simplified and scrappy version of what I called hanging square in square. This one has a 9 patch square in square (or simple courthouse steps), 3 units by 3 units and an elongated rail fence block, 3 units by 5 units. I've usually seen it done in 3 colors, 1 dark, 1 medium and 1 light. One column is dark + light, and then one column is medium + light.
