Fimo Classic Polymer Clay
I originally got "Original Sculpey" but it turned out to be too soft. Being about 33 degrees Celsius outside didn't help either. Also I did not want to wait for the plasticizer to soak out (layering it between pieces of paper, adding a weight on top, waiting a few hours), so I went to Michaels and got some Fimo.
Any brand will do. Make sure the clip size matches the skeleton height you want to use.
Pottery shaping tools
$10 from amazon for a decent set
Clean working environment
Plasticizer can leach from the clay itself so it is important to protect all surfaces and to wash your hands before eating/using the computer.
