I just painted my with camo paint as a base coat. Then held some various sticks and leaves and such as I shot some other camo paint colors on it. Make sure you mask off the parts you don't want to paint. It's really no big deal and I promise predators don't rally care if it looks fancy to the human eye, but HEY! It might impress your buddies if it looks fancy. It's almost like laying sod, it's pretty hard to screw up but mask the areas you don't want to paint and go for it.
Good luck! Don't worry, be happy.....
