There is probably a pattern for PPing it somewhere out there. Additionally, I believe it can be made using Pam Bono's technique of sewing two rectangles together corner to corner diagonally but I have never tried experimenting with it. Doing it this way you would end up with a center seam in the large equlateral triangle. Another option would be making them kind of like I make FG units by sewing a square to either side of a rectangle on the diagonal only instead of a square for the 54 40 or Fight it would be a rectangle. Hmmm, makes me want to experiment some.
