Anneka and Will are each supposed to have some dolls of their own in 1:6 scale, but I’ve had a horrible time finding affordable figures in the 1:36ish range…until now. The Homies series of plastic figures, all 2" high or less, presents models of various urban characters, one set of which, the Micro Icon Punks, would be perfect for Anneka and Will’s dolls. But I still need to make at least one mermaid for Anneka and a Bru for Will…maybe out of paper…
Barclay’s O Gauge Corner sells O gauge [1:48] civilian figures for reasonable prices.
Here’s a 1:12 scale girl doll [by Sophie Drummond?] that might work as Will’s Bru.
