A few have wigs, which I'm not sure I like, two have yarn reroots, which I love, and the rest have all or most of their original hair. (I had to trim the frizzy ends off the pink haired Finger Ding girl.)
All three Finger Ding doll heads are on Hildy bodies.
Hildy and Spunky yarn reroots.
I still have a small pile of extra bodies and heads to work on. I'll be selling some of them with new outfits. :)
