One of the best resources on the web for polymer clay miniatures is the incredible resource that Nora Jean provides with her sites. I’m linking to the guava tute but she has literally dozens (probably hundreds) of tutorials scattered throughout her sites. It’s well worth a look and poke.
A bit of background here is that while I’m a caning and beads sort of clayer my daughter is a miniatures loving clayer. Pretty much all the miniatures I’ve attempted have been to curry favour with my kiddo but as with all things clay the techniques apply across the board. Caning is used extensively in minis, careful construction and “faux” everything is used in bead making.
