I do i paint fondant to look like wood like they do on ace of cakes?
I'm not sure how they do it on Ace of Cakes but I have an easy way. In my cakes there's a tree and a wood base to a snowglobe I made. With these I covered in white fondant then made lines with a knife &/or a toothpick. Then I took the Wilton brown and mixed it with a little alcohol then just slowly brushed it on. HTH!! Good Luck!
