We've been working on hands in the Santa Workshop (you can join here). I was going over Jack Johnston's book and his chapter on hands, and I thought it would make a create little pass along PDF. Here is you copy to download and learn from. Feel free to send your friends to this page to download their own, or you are welcome to just email it to them. It's a nice guide to have handy as you are sculpting. Sometimes static pictures are a good addition to the sculpting videos.
