I think I am on the right track. I don't like the way they look, but it was my first time trying it and I had no idea what I was doing. The middle fingers are way, way too big, and the pinky fingers look like penises. I need to figure out a better way to build up the fingers, I think.
Anyway, here is the resulting video:
So...notes for next pair...
1. Use something easier to manipulate to build up fingers. Something that won't flatten when pinched.
2. Don't make fingers look like penises.
3. Get rid of bubbles in latex so paint doesn't chip off.
4. Make them in proportion to the puppet.
That last one is hard. I have never been good at judging quantity, whether it is how many of something I need, or size. I think I can get something useable though.
