Does anyone else have a favorite type of joint on a doll? Or a favorite joint system on a particular doll/doll line? I really really love Fairyland's knees. The kneecaps are genius! It's my favorite alternative to the knee-bean look. I can't help but bend my minifees' legs a lot because it's so satisfying seeing the knee joint work so smoothly. I'm also a huge fan of underbust joints for both male and female dolls, even if they don't offer too much in mobility on their own, they usually look seamless and so aesthetically pleasing!
