Above, from the good people at Barnes, sculpture supplies. "Clone FX with a plaster bandage case mould. A great cost effective mould making solution." To see their full range of tutorials click here.
Press casting with Super Sculpey, above. David Neat has an encyclopedic modelmaker's reference blog and his advice is informed by years of practice. His section on Modelmaking Basics is "The third of five outline accounts dealing with what I consider to be the five defining areas of model-making work; main construction, fine construction, modelling/shaping, creating surfaces and painting. I'v written these overviews in preparation for teaching sessions at RADA (Royal Academy of Dramatic Art) in London. So they’re tuned towards the specialities of theatre design model work, but most of the points will be relevant in general terms to model work in other disciplines."
For the low down on Super Sculpey click here. My tip: get yourself some Super Sculpey Softener from Barnes. Stops hands & fingers cramping from kneading cold Sculpey. The generosity of David's knowledge sharing on this site is truly marvellous.
