Get triple use out of gift bags

I'm awash in gift bags now that the holidays are over, so I can't imagine buying one ever again (plus I'm down on disposable wrapping in general). For some people, though, a new gift bag is part of the gift. From Jen:

My mother invented protocol for using gift bags, When she first gives a gift in a gift bag she buys, she doesn't write on the attached tag. This gives the receiver the opportunity to re-use the bag again. To use it a third time, rip off that paper tag, and put on your own. This has saved me many trips running to the store for gift wrappings, as I have a small arsenal on hand now. Reuse reuse reuse!

Another great reuse for old gift bags -- I cut them up for use in craft projects. The hard, shiny paper often works well as an embellishment for handmade cards. They're good makeshift lunch bags. They also make good car totes...keep a few in the car to help kids gather things to bring inside after a trip.

Any other handy uses for old gift bags?
