I finally finished all of these stars. And now I've arranged them on my design wall.
I first tried a straight set, but that seemed kind of dull. I like the diagonal set much more; it looks more dynamic.
I used as many of the blocks as I could, but there were a few left over. Also, because there are equal numbers of light and dark blocks, I ended up with dark blocks along two sides and light blocks on the other two sides. Later, I will cut dark and light border triangles to finish the diagonal rows.
