I'm a great fan of jointed hands: I purchased them for my first doll back in 2009.
But I discovered soon that they were too unstable for my taste: didn't hold the poses as I liked, the precision of gestures wasn't perfect.
I've heard of wiring that people did to their DollShes and Volks to improve their posability. So I thought: why not wire the jointed hands?
I was the first one to do that.
Eventually I found a great wire for that purpose, so I created a tutorial on wiring.
