1. Soft Nose Putty.
(You could use the regular stuff it will just be a pain.)
2. Make-up Kit.
(Get a decent 5 color kit. Flesh tones and reds and yellows.)
3. Spirit Gum.
(For sticking stuff together.)
4. Tooth Blackout.
(There is a wax based kind and a paint on kind. Both work fine.)
5. Some Fake Blood.
(I always have some corn syrup, red food coloring and chocolate syrup on hand!)
