I still find these suckers under my kitchen sink in giant wads as though they have taken a liking to one another and started breeding.  Therefore, I am left with no choice other than find useful, creative ways to repurpose them, as any savvy girl would.  If you've got a few uses of your own, please add them in the comments and let's try to rid ourselves of them forever.

1. Foot Covers: Cleaning the shower from top to bottom requires climbing in the shower itself and for savvistas who hate getting scouring powder on their feet only to run the risk of accidentally bleaching a towel or staining the floor, plastic bags make excellent foot covers.  Just step in one and use the handles to tie snugly around your ankle.  This works great if you're cleaning up your patio as well and don't want to drag dirt in from your shoes or bare feet.
2. Shower Cap: Do I own a shower cap? No siree, but I make one regularly out of a plastic bag.  Just put the straight-edge of the bag against your forehead and wrap the rest 'do-rag-like around the bulk of your hair.  It's not a fashion statement, but it works.
3. Gift Wrap: This is not for everyone, but for your like-minded savvista friends who will get a kick out of your eco-craftiness, you can make a nice gift wrap out of 2 or 3 different colored bags.  Just place one bag inside the other, insert your gift, tie with a pretty ribbon and trim the tops stylishly.  It has a tissue-paper effect and is rather lovely.
4. Dirty Job "Mittens": Similar to the foot covers, plastic bags work great for those dirty jobs when you don't have gloves lying around.  Dog-doo, baby-poo, dead mice, insects, or even if you have an aversion to touching raw meat, removing innards from poultry, cleaning toilets, whatever doesn't float your boat.  Plastic bags do the job nicely.
5. Package Filler: Skip the pricey bubble wrap and use plastic bags instead.  This will work best on smaller packages, but think how happy your recipient will be to inherit your collection and put it to work!
