I'd like to paint a fondant flag to be draped over a buttercream camo cake for a returning serviceman for next weekend. It'll be my first attempt at painting. Does anyone have any tips they can share? I think I read here on CC to use vodka, but how does that affect the taste? And can I just use Wilton colors or is there a special type of "paint" I should get?

Thank you so much for your guidance!!

Just you whatever color you have and dilute it some with Vodka and paint away. You want to dilute it because if you don't it will take forever to dry, and will still be a little tacky after it dries. The vodka doesn't leave a taste that I have noticed and evaporates off faster than water. If you have airbrush paints you could use that too, it dries a little faster.

painting on fondant is really fun & not hard IMO. I used my Americolor gel colors straight for a deeper cooler and just paint on with a paintbrush you use for food items.
another option is the Americolor food pens

Thank you for the advice...CC has been so invaluable to me!!
