there are at least two different ways to make the block:
(1) reduce it to squares and half-square-triangles
(2) divide each block into 3 rows divided diagonally halfway across
i've attached rotary instructions for method 1 and templates for method 2. (i would use the template as a rotary cutting guide)
each will make a 9-inch block.
4 blocks make 1 star.
