Gumpaste will work for sure! It will be rolled thin enough that it should dry out in less than a day. I've managed to dry some thin pieces for picture frames overnight... but it's not humid in my area.
Can you possibly put them in a very low heated oven for a few hours to speed up the drying?
I believe you! I tested the blade with my fingernail and WOW is that ever sharp. I see why its so effective.
I plan to do a happy dance and destroy the heck out of my wilton wire leveller this evening :D
Mine arrived today!! So exciting, I assembled it right away and then realized I have nothing to test it on. I have bread and I'm actually tempted to slice it just for fun... even though it's presliced bread. I have issues lol.
Guess I need to bake something tonight!
