So I started just trying to learn the diagonal seams method to make these stars. I figured by the time I had enough stars to make this, I'd be better at making the stars but... didn't quite work out that way. I don't know why I have such a hard time with it.
But there it is. The points on the stars are cut off because my star blocks would come out so wonky that I'd have to square them beyond the seam allowance.
But once I got to matching up the seams for the blocks and rows I feel better about my work.
