Here's some ideas that I've used them for! Crayon box, trash box for the car and small puzzle box. I've also used it to store baby socks in a drawer. You'd be amazed at how many matchbox cars can fit in one. This one comes in really handy: I've made a baby emergency supply box with it. You can fit 1-2 diapers, a snack baggie with baby wipes in it, a sample size diaper cream, formula packets, a sample size lanolin cream (if you breastfeed). This always stays in your car. There's been more than one ocassion where I thought my diaper bag was all set to go, only to find out that I was missing something. So it's perfect in a pinch. I also make a mommy version for the car, too. Tampons, pads, breast pads, hair ties, extra underwear, toilet paper, tissue, gum/mint, lotion, lip balm. You can also make your 'emergency kit' for your desk at work. And make first aid kits for each bathroom.
At one time, I think I had about 11 all over the house. You can decorate them really cute if you are artsy!
The possibilities are endless! Have fun!
