The first block was the chain block. I didn't really have any trouble sewing the curves, and I attribute that to making cloth dolls (lots of curves there!).
The second block was to be Cleopatra's Puzzle, but I chose to make this variation, which is basically Cleo's block with the center four squares rearranged a bit. Of course, after I took the photo I noticed some misalignment of the circle in the center. I have since unpicked that section and fixed the eye-sore.
Only two more blocks to go!
