Last year, there was a thread about things to put in your bag to have with you between rounds. That list got pretty long - it would be a pretty full bag so when I couldn't find the old list, I figured we might as well start a new one.
I saw this on sale at J.Crew and thought it perfect for a nervous PNM. Especially since now you might only be able to have a small bag.

It includes: hairspray, glitter nail polish, emery board, lip balm, earring backs, hair bands, barrettes, facial tissues, breath freshener, emergency info card and sparkly adhesive bandages.
I think the only things missing are a notebook, pen, and a paperback to read during the break. Maybe some safety pins?
