I teach dance classes at the local gym/athletic club, so my bag is probably a bit different than everyone elses:
*Leg Warmers* (80's yes I know, but as much as I dance some days-I need to keep my ankles and calves warm-they were a dancer staple before they were a fashion statement.

)
*Class Sign In Sheet*
*Music CD's* (for class)
*3 yard veil-extra light habotai silk*
*Saroyan Finger Cymbals*
*Class Itinerary/Choreography Sheets*
*Handouts for class, if needed*
*Muscle Rub*
*Bottle Of Water*
*Pen-Pilot V5 Extra Fine* (I only write with a certain kind.

)
*Hip Scarf/Wrap*
*Safety Pins*
*Lip Balm/Gloss*
*Lyric Sandals* (dance sandals that basically keep your toes/heel barefoot, but they strap on and protect the balls of your feet.)
I think that is it on most days...
