I’m not one to share secrets, but this one is just too good to keep to myself!
If you are using silicone moulds for polymer clay or PMC, do you find it can get a bit squished when you try to get it out? I do, especially with deep moulds, like Lego bricks. The answer is so simple I could slap myself. Put your clay in the mould as usual, and freeze it. Then it goes nice and hard and is easy to get out. Once it’s defrosted, you can add surface details. And then fire as usual 🙂 Who knew?
