My cowboy hat brim isnt drying fast enough for tomorrow. How long does gumpaste take to dry?
It depends on the recipe you used and the weather where you are.
Is it hot and dry? Rainy? Did you use Bakels(sp?) gp? (I hope not!)
Usually overnight should do it. You can hurry it along a bit by putting it in the oven with just the light on. Be sure you put a note on the control so you don't forget and turn the oven on!
Kakeladi's right - drying time will vary based on the weather. You can also try putting it under a fan, or a gooseneck lamp, just not so close that it will scorch.
