How do I Airbrush Lustre a Wedding Cake

My friend Karen Hill who owns Wedding Cake Art teaches this technique.

It is so easy to do with an air brush but it it can be done dry brushed. The secret is to layer the colors. You will need some Lustre Pigments . Make sure you keep your machine's tip clean and clear of blockages  with liquid cleaner . Make sure you are in a well ventilated room.
