I'm thinking of trying my hand at some simple sculpting and/or conversion for the 15mm scale. I intend to buy some Green Stuff (or the local equivalent, which is grey or yellow) and a sculpting knife and try sculpting simple things such as maybe a giant serpent, giant worms and so on (later I'll try a giant toad).
Once the sculpt is done and hardened, can I prime and paint it directly or are there more steps to be done?
Do you have any advice to share with a sculpting newbie such as myself?
