Do: Splurge on cute designs.

It makes even a boring turkey sandwich seem exciting. I love the fun Mobi bags (they even just launched a collection with Todd Oldham, shown left). But you also need to check out this anti-theft bag design I found via LifeHacker.com. It has an artfully placed green-splotch design intended to ward off office mates and grammar school bullies with sticky fingers. Before you say, what a waste...

Do: Wash your bags.

I stick mine in the dishwasher and re-use until there's a tear in the side or if something unappetizing was in the bag. Admittedly, if you don't prop them up right in the dishwasher, you end up with a bag full of water. If this really concerns you, buy the Bag-E-Wash which holds the bags upright to allow maximize sterilization.

Do: Re-use your bags in clever ways.

Always on the hunt for new uses, here are some ideas from the Real Simple vault: use a sandwich bag to refill a pepper grinder, organize jewelry, and store beauty products.

Do: Use them for portion control.

I usually buy a big bag of trail mix or other nut mixes at Costco, and then fill up a small baggie to take to work with me every day. If I had that whole big bag at my desk, I would probably mindlessly munch on it the whole day.

Well, I don't really have any "Don'ts" per say...but let me know if you do! Or if you have any other ideas to add to this list.
