I looked over the picture really good and this is how I think it is designed using a Jelly roll. You make the blocks with different fabrics in the different positions and just turn the blocks until you like the design.
it's 4 rows wide and will finish at 8x8. The following are finished rows
2 -4 inch, rectangles
4 - 2 inch squares
1 - 8 inch long strip
A 6 inch and a 2 inch
