what temp and for how long?

my pieces are 1" x 2" x 1/4" thick. i cut them last night, and i need them by tomorrow morning...preferably i'd like to assemble my piece tonight.

thank you-

If it's a gas oven, DON'T turn on the heat, the pilot and light will do the trick. An electric oven, I have no idea but you don't want more than about 110 degrees. (That's a hot day, no more.) If you have a convection oven, see if you can manually turn on the fan, that will help. If things become panic ridden, try a hair dryer. Good Luck!

Edited to add: a couple of hours should produce a solid feeling piece. Dry on the outside but still moist inside. At this point, they should have no problem holding their shape.

wonderful. thank you!

Anyone have any tips for a gas oven w/out a light?

I turn the electric oven to 200 degrees, leave the door open, and set a cookie sheet with the decorations on the door. That way, they are still getting heat, but they are not actually in the oven. HTH

Thanks, mlharvell, that makes sense.
