501 Rotary Cut Quilt Blocks (That Patchwork Place). I love the pinwheel effect of the light/dark placement on the half-square triangles. And how the effect continues into the suggested border. It almost looks like the paper has been folded along the diagonals.

Due date for this block is March 16th. I won't make the border, so it should be quite doable.
