I created a unique and utterly cheap invention this past week and thought I'd share!
When I lived in my old house, I cooked all my sculpy in the oven. My wife didnt care for it too much, so when we moved, she asked that I not do it anymore. Well, this put a real monkeywrench in my customizing. I tried using a hair dryer, but it took forever, even though it did accomplish it over time.
So, I got a bright idea one day.
I took a cardboard box about 4" all around (square) and left the top open. I taped down thick aluminum foil to all sides. Then, I cut a hole out a little bigger than the end of my hair dryer. I taped shut the top all except for one side which I could open and close to put my object inside. Along the bottom, I put a few holes for vents.
Stick your hairdryer in the hole and put the sculpy object inside and hit high heat for about 5 minutes. Its done! Really its your own easy-bake oven!
It works perfect for me now! I'll try and post pics but its really simplistic.
