Thank you very much for the feedback! Those two things are exactly what I was worried about with this idea. I have only tried airbrushing on posterboard so far but I noticed that it stays tacky and that definitely isn;t going to work. Has anyone found any brands of airbrush color that do not do this? I also wouldn’t want the black to have a shiny look since the alternating red tiers will be with colored red fondant since I am doing a billow effect on them.
Darn! I may still try and play with this but its not looking like it will work for this cake! Back to fondant hunting!
