One of the things I hate about women's clothing is about half my clothes don't have pockets. (I almost always wear skirts: it's a personal quirk.) At the same time, I want to be able to find cards, etc. in my larger bag quickly.

A couple of years ago, a friend gave me 5 small sewn pouches in different colors, with a string cord. (similar to here only mine are made of a velvety material, have a zipper near the top on one side, and have a smaller design)

The pouch is big enough to hold a few cards easily (ATM card, health insurance card, car insurance card, driver's license, library card, plus a couple of membership cards for places), some bills, and change. (I dump it out when it gets too heavy, but the coins automatically fall to the bottom.) It's a tight fit to get my key fob + two keys in there, but I can do it.

The cool thing is that if I don't need my bigger bag (going in the grocery store, running into the library, etc.) I just grab the list of stuff I need (on index cards), sling the small pouch over a shoulder or around my neck, and I'm good. Doesn't matter if I'm wearing something with pockets or not. The string also makes it easy to find in the bottom of the bag.

The gift was part of a holiday exchange gift (I think it was a $12 limit), so they're very cheap, and also help support local immigrant communities. I've seen similar stuff at museums, farmers markets, and other places like that. I used one of the pouches non-stop for 2.5 years, and only recently retired it when it started looking really ratty.

I use another one in my larger bag for a mini-med kit (asthma inhaler, a few ibuprofen, bandaids, etc.) too.
