I've made a unicorn horn with Renshaw modelling paste. It's very wet and I need it to dry in time for DDs party tomorrow morning. I've tried blow drying a spare piece of the paste to see if that helps it to dry without it cracking, and it seems to be ok, but I'm wondering if putting it in the oven on a low heat for a while would be better. I'll be honest, it looks pretty crap anyway, but I don't want to make it look any worse. Any suggestions?
