I made a shoe with sugarpaste, there are ways to dry more quickly
Are you asking how to make it dry quicker? If so, try putting it in your oven with just the light on. Do NOT turn the oven on, just the oven light.
You can definetly put a fan on it. I do this all the time. I have also dried in over (electric) with temp. on 150F..66c. Nick Lodge and Scott woolley , both say this. You leave in for at least 2 hrs. I used this way when i made my fair cake for leaves ,etc. worked great. hth
I dry my gumpaste items in my oven with the light on, but I keep the door wedged open about 1-2 inches. Once I closed the door completely with the light on and it was too warm for the gumpaste and it started to melt. So make sure there is not too much heat in your oven if you close the door completely.
