Take some leather and wrap your possessions in it. Now you have a bag to carry them around in. Neat!

You actually learned this reading with the vocabulary word カバン. It's been a while though, so here's a mnemonic to help you connect it to this kanji:

The reason you made your own bag is that there's been a car ban (かばん). With this car ban, you can't just throw all your stuff in your car anymore (come on — we all know you were using it like a second closet) so now you need a bag to carry it around in.
