Well, it's done. And it snaps. And I love the wind-up robot fabric. But I tried to use felt for a layer inside and it was too thick. Plus then I sandwiched it wrong and so the felt is one the back, not in the middle. Which isn't so bad, it's red so it matches fine. But I learned you gotta really trim the seam allowance where the snaps are going to go, otherwise there will be too much fabric to push through. Also, hammer the pearl top part of the snap on a soft surface, like I did here on folded up felt, so you won't crack the pretty top.
So! Third time should be a charm, eh?
