Help!!! My son is getting married in April and wants me to do his grooms cake, I do bake, he wants it in camouflage and hunting. I want to do the fondat in camo colors but don't really know how can anyone help?

I like to take pieces of the different colors for the camo and mash them together, then roll out. If he is picky about the style of camo (like digis) I don't think it could be done this way but otherwise it works well. Good luck!

As mgdqueen said, it's rather easy to take pieces of fondant, add green, brown, and whatever other color wanted; push them together into a ball and roll it out. Don't knead it too much or the colors will blend.
As for the actual decorating I really can;'t say much. I'll think on it if you need help
