Recycle Holiday Gift Cards

It's been a good year for my husband, who is a High School English Teacher. Every year at this time we get a flood of gift cards (happily accepted).

Up to now, after they were used up, I would struggle to toss some out because some are really cool looking. Honestly. Some stores actually put thought into the design (Target, Starbucks, iTunes).

The other looming question: Will the cards be collectible someday?

I now have a great Right-Brainy way to re-cycle them thanks to a random comment to a comment on a blog. No joke.
(Debbie Jordan Kravitz of Virtually Organized asked her followers on Twitter what we couldn't live without.
I said nose strips. I stand by it.
Paul Merrill, a rubbish artist in Colorado, commented that he has a post similar.)
and here comes the winning comment:

An idea for recycling: Ian cuts these up into guitar picks!
Yay! A great used for cool, hip plastic.

Another idea: Ice scraper for car windows

What else can you do you do with your used gift cards? (besides tossing them)
