Each time you’re baking it in the oven, how long are you baking it for? The polymer clay I usually use is a 30 minute bake so are you only part baking (say 10 minutes) each time or are you baking for the full time? Thank you.
I don't understand why you baked the initial house when it was made out of a cardboard box, but then didn't bake any of the rest of the house. does it just get hard on its own?
She mentions that she baked it several times throughout the process to keep delicate areas from messing up. The first bake is so the clay on the cardboard hardens and makes it easier to work with. None of this gets hard on its own because polymer clay requires baking to harden. Only air dry clay will harden on its own. Hope that helps.
I made my own polymerclay gingerbread house and used a cardboard base to save some clay. After that I put the cardboard with my clay in the oven. For the first time I was afraid and didn't moved from my oven, but everything turned out well. I used Fimo and the temperature was about 110 degress.
You're welcome. I started wird polymer clay a couple of weeks ago and experiment a lot. Gingerbread houses are really nice to make. You can buy nail art supplies and use it for decoration.
