Does anyone know where I can get hold of coloured polymer clay (ie.
FIMO) in the UK?
Try any art supply or hobby shop. Also Craft Kingdom in Hereford, and
HobbyCraft which has branches in Bournemouth, Southampton, Gloucester,
Northampton, Bristol, Tamworth and Sheffield. Fimo and Sculpey are widely
available. You can also get Fimo by mail order from various places, including
the Brighton Bead Shop, Fred Aldous, Manchester Minerals, Earring Things, etc.
Check the adverts in craft magazines for mail order suppliers.
HTH & good luck,
