Book Worm Bands

I have finally purchased a Kindle. I don't have a smartphone, and I will be traveling enough this year that I decided it would be worth it. About a week after it arrived, I woke up one morning and remembered this elastic I'd been saving because it said "book worm," hoping to find a suitable use for it. Where did I find this awesome elastic? It came off a pair of underwear. Since it was from the waistband, it was long enough to cut in half and make two bands. I suspect they will be mostly decorative, but they can be used to hold the case shut, or secure other items.
