With this shape in a layout of 4 alike it is the Kansas Dugout traditional block. The only difference is the traditional block has a square set in to the hole made by 4 of the diagonal shape instead of 4 triangles making the square. I just put the blocks up randomly on the design wall and figured I will play with the layout today. But, I'm pretty happy with it just the way it is.
I looked at it from a different angle.......not sure if I'll move the blocks around. I could put them in top to bottom columns of similar colors but there are 5 columns and only 4 main colors. It will get sewn together today. There are 30 blocks and 28 different Marcia Derse prints used in the diagonal shape. It should finish about 60" x 72".
