What to do with that fat stack of last year's Christmas cards you've got stashed in a drawer? Well, if they're photo cards, save 'em. But if you've collected some cards with holiday-themed graphics, Real Simple says [1] repurpose them! Cut up that old stationery into festive shapes like stars, Christmas trees, and ornaments. Then, scribe each of your guests name on the paper, hole punch, and tie the place card to your napkin with a ribbon or some red yarn. I have a few of my own holiday card repurposing ideas for you, so .

• If there is no writing on the backside of your card cover (where the image is), you can cut off the top fold and use it as a postcard, writing your message on the blank back side.
• You can slice card covers into four to six different rectangles and use them as gift tags. Punch a hole in the card and slide it onto your ribbon before you tie your bow.
• Cut the card covers into festive shapes like Christmas trees, ornaments, and stars. Then punch a hole, and tie a loop through it with ribbon. Then, use it as an ornament on your tree. You can add additional ornamentation with glitter, beading, etc.
• Cut the card covers into star shapes and letters to spell out "Merry Christmas." Then, make a garland out of them by stringing them together with red baker's twine, yarn, or ribbon.
• Buy a pack of blank note cards. Cut up a few card covers into different shapes or stripes, and collage them with Mod Podge glue onto the front of the blank note card.
• Or, you can send them to St. Jude's Ranch for Children [2], a safe home that rescues abused, abandoned, and neglected children. It runs a 30-year-old recycling card program to benefit the children. The children participate in the program by making new cards removing the front of donated ones and attaching a new back made with recycled paper, and then they are sold. Cards may be donated by sending them to:
