I have painted my cala lily gumpaste flowers orange (mixture of golden yellow, lemon yellow and red) and lemon yellow gel wilton icing colours last night.
I did not have alcohol/vodka on hand so I painted the flowers as is. I need them to dry by this Thursday. Any tips, suggestions to get these flowers to dry quickly will be appreciated.

I have put mine in the oven with only the light on and that speeds it up a little. I don't turn the oven on but the light seems to give off just enough heat to help.

I think they'll dry by Thursday just sitting out. That's 2 days. Did you thin out the gel color with anything?

Limestone absorbs moisture, so if you placed it in a re-sealable container, placed some limestone in a small cup with the flower and then covered them, that would prob. work! We used this method with sugar work in school.
