I made my first ball-and-socket joint that blogger Jonty at Darkside Creations had developed and which I discussed a couple of weeks ago. I call it a "Jonty Joint."
Jonty recommends using balls about the size of ones you'd find in kids ball rooms. The only ones I could find like that came in a bag of 100 which I figured was a few more than I needed. So I used Wiffle balls instead, even though they're a little larger. However, they seem to be a good size to replicate a shoulder joint and if I can come across some smaller balls (maybe between golf ball size and the one's Jonty recommends) it would be good for an elbow, wrist, or knee.
Otherwise the joint works just like it's advertised. It's a quick project that gives me another dimension in posing my props.
