Block 5, the Batwing, has 5 pattern pieces. I was seam ripping a few times to get the triangles to create that perfect point THEN to have the point show up when you sew the middle section on.
Block 6, I really like this one. This block has 8 points that you have to be dead on to get the pinwheel effect.
When I finished these two I started searching for the colors for Block 7 and 8. Think I’ve got it.
