I carry as little weight as possible.
Stuff in bathroom drawer. Stuff in gym locker. Stuff decanted ready for travel (nylon stuff-sacks or zip-ups: "make-up, clean-up, hair, meds" is the mantra that gets everything packed).
Lightweight purse organizer has mostly "other stuff" that weighs too much but I can't seem to do without (notebook, pens, index cards, business cards, wallet, phone, digital recorder, headphones, glasses, glasses cleaner, lenses and solution) and a small nylon pouch with comb, small brush, lip balm, lippie).
Contact lens cases for stuff for travel??? Oh! Oh! Oh!
