what else to offer

So my husband does balloon animals, and I do face painting. I have seen that some of you do glitter tattoos, and I'm thinking about adding that to our list since we have several children who are old enough and want to help. Is that a good place to start, or would plain old temporary tattoos be better? Where could I get temporary tattoos in bulk? Are the glitter tattoos worth messing with? Are they easy enough for young teens to do?

very easy to do. I was just at a school carnival and I informed their youth group about them and they had no problem doing it.

I've done a couple of them (with glitterfly's supplies) and they are not hard to do, they just take a lot more supplies than face painting does. Stencils, glue, LOTS of glitter, brushes, alcohol and cotton pads.... I don't have the money to invest in it right now.
