Puppet progress (tired)

I worked on the thumb control for two days, then had to scrap the whole design and start

over. This fabrication process generally takes me longer than I would like; this is because its all trial and error: I'm rarely building a mechanism that I've made before in some other puppet. Mechanical elements from show to show are pretty unique depending on the needs of the puppet. First time for needing a chimp's bottom lip to curl.

OK. So how do I do that? Hmmmm. Try again...
