I am working more with fondant. I saw on a TV show where they were making a purse covering it with fondant and they were painting a design on the purse. What type of coloring do you use to paint on fondant? Is it just your basic paste coloring that you use in buttercream?
Yes, that's the simplest thing to use. Mix it with vodka or a clear extract to get it thin enough. You can also paint with petal dust or luster dust mixed with vodka. Use a paintbrush that hasn't been used for regular paints, but it doesn't have to be a special cake decorating paintbrush...I use the regular artists paintbrushes because they're better and cheaper than the Wilton paintbrushes.
Ditto above. I mix to the consistency of maple syrup.
