While I was ASM for Come Blow Your Horn this previous spring I had a set of plastic boxes separated into office supplies and first aid stuff in my cubby in the technical directors office. I had several types of Band-Aids including Hello Kitty, Spider Man, and several types of flesh tone one. Apparently at some point during Act I the actor playing Alan cut his finger on an exposed nail, or something (I really don't know any of the specifics because once tech week started I took off my ASM hat and put on my Lighting Designer/Board Op hat). During Intermission the SM was running around like a chicken with her head cut off because she was unable to find any Band-Aids in the theatres first aid kit. The actor reminded her of my stock pile of first aid and she started franticly rummaging through my box, which I am still a little resentful about because it was all out of order after that. All she was able to find was the spiderman ones that were in a mini first aid kit. Some one passing by and noticed the insanity in the office pointed out the several boxes of the fleshy ones. She handed the actor one of those and he started pouting. He wanted the spiderman ones and was certain it wouldn't be a problem because Stan Lee was alive in 1961.
Goodness that was a long winded anecdote. I guess the point of it was that the absurdly bright and colorful Band-Aids are a huge pick me up for the inner 3 year old of any injured actor.
As for my SM kit, it is currently made up of the 2 previously mentioned boxes over flowing with medical supplies and office supplies. As well as a travel toiletry bag (the kind that roll up and have a hook at the top) that I fill with this things I am most likely to need during a rehearsal, things like post its, pencils (for actors), white out, bobby pins, hair ties, erasers, dry erase and wet erase markers, sharpies in various shades, mini first aid kit, and a mini sewing kit. I hang it on the back of my chair for easy access during rehearsal. There is also an other smaller make up bag of sorts that I carry along with me everywhere (mostly because I hate to feel like I'm not ready for anything, and I'm a little OCD) that has post its, pencils (for me), highlighters, pens, sharpies, tissues, and hand sanitizer
