I used a combination of precolored fondant and fondant I colored myself for the wood and leaves. For the leaves, I just tinted white fondant different autumnal colors (with Wilton paste food colors) and then mixed a couple together and rolled them out. The key is to not mix them so much that the different colors totally blend together since you want to see the differences. I learned this through trial and error ;o) For the wood, I started with chocolate fondant and then tinted some a shade lighter and some a few shades darker. I mixed them together and rolled it out (you want to end up with kind of a swirled effect). Then I made line and ‘hole’ impressions in the “wood’ and went over them with a food safe dark brown marker. I haven’t been doing this very long so I don’t have much experience with fondant painting yet and for a small cake like this one (it was two 6 inch rounds) it was easy and fast to color the fondant.
P.S. I took the cake to a get together last night and people really liked the decorations but also LOVED Rose’s cake and frosting. Woo hoo!
