I have a box of out-of-date business cards, what can I do with them?

The email address is no longer valid and I paid $30 for a thousand of them of which I probably have 800 left. Any craft ideas?

As much as I'd like to reuse them, I'm a photographer and have since moved from plain white cards with black raised ink to full color business cards. Remarking the old cards doesn't work for the people I deal with.

Use them to cut stencils out of? :o

Or you could wind thread around them for embroidery, etc. Just cut notches in the ends.

Or you could go crazy and glue stuff to them and make tiny, tiny holiday cards n_n

Can always use them to test different mediums on (scrap paper for testing paints/colors/finishes, etc)

can you use a lable maker to cover up the old email addy?
or just use a blk marker to cover it up

You could easily donate them to the closest school or club for kids, where they can use it for art projects.

Or you could even make a little card game out of them (the kind of cards you'd get from monopoly.) Plus, the game could either be adult oriented (with your love one,) or something that could be play with kids (like, mix or match the aliens/bodies/styles/ect.)

For myself, I'd use them to make tags for scrapbooking. Maybe some crafters could use them.
Or bookmarks, magazine marks.

i would use them for notes or recycle them

Our you can send them to a collector to be used for trading stock or prizes for games that collectors have from time to time.As a collector of business cards if I have any extra's then I trade with other collectors for different cards...So I could always use extra cards .
