It's great. I love pinwheels. Saw a video the other day on how to make HST faster, easier. Take two squares, place right sides together, sew 1/4 seam around all four sides. Then cut on from corner to corner as if you were cutting 2 triangles, do it again from other direction, and you have 4 perfect HST to put into a pinwheel. I tried it and it works great. No more sewing triangles together.
