I see a 16 patch block that is made up of 4 sets of 4 patches. I am assuming that it finishes as an 8 inch block when you combine all the 4 patches together. The other block is an 8 inch finished block that has the first curve in each corner at the 2 inch mark. The second curve is in the middle at the 4 inch block. It probably should be paper pieced.
Edited to Add: On second thought, the curved block would probably be better as templates. They should be fairly easy to draw using grid paper.
