As I was working on a bear yesterday, I though it would be fun to show you what allows my bear arms to bend and hold their poses. It is simply a wire armature that I make. There are some available for purchase, but mine are more economical and so easy to make. I get my supplies at the hardware store.
I think the photos explain the process - be sure to click to enlarge them for a better look.
Oh, and watch for a new bear soon !
