Bought a nice kit from 3d casting kits at babyrice.com includes frame , white card and everything you need.
Heres after the foot was done ...
and finally the finished article, note its left 'natural' colour. I didnt use the silver paint in the kit, as i think it looks better (and a little less freaky looking lol)
Top notch service from http://www.babyrice.co.uk/, I did in fact drop the glass from the frame which they replaced FOC the next day! Amazing and really something in this day and age.
Top kit , Top business. Get one and try it out for yourself
