*POST INCLUDES PICTURES OF PENIS COOKIES*

I recently started using an airbrush to save a ton of time with decorating cookies. I ice them with white royal icing. The next day I decorate them with an airbrush. The day after that I use edible marker for details and then bag them up to ship. I went to ship some cookies and noticed the airbrush color had changed slightly and become wet again. um, wth! How long do I need to wait for this stuff to dry? it was dry to the touch when I bagged them. 

PLEASE HELP ME!! 

The icing is absorbing the moisture in the cookies.  Airbrushing really has nothing to do with it.  You'll have to bake the cookies longer &/or leave them dry longer before icing them.
