Cards can be tons of fun for very little cost, but the biggest down side is that the entire deck becomes useless once you lose so much as one of them. And no matter how careful you are with putting each and every card back in its box, the mysterious card napper (a distant cousin of the left sock stealer) will eventually find a way to make off with one or two, or 17, if you're me.
And so, in the spirit of upcycling, why not use your past failures to help you organize and keep track of other things so that you won't as easily lose them?

...And then grab a cute mini paper punch...
...and punch out holes for small dangle earrings!
