When I tried this, it is very hard and grainy. After a while of mixing, even though i got it into a round ball, i had grains still coming off it.
The way I use it currently, I mix it with some regular super sculpey. I am now thinking I am getting rid of it's best property..the ability to carve rigid details for faces, etc.
I need to ask those more experienced (I do this for hobby purposes): what is the best way to mix/use firm super sculpey?
