I was inspired by Patricia's post and Ellie's business cards to make some tiny Valentine's Day notecards using washi tape and baker's twine. These little babies are 2.25" square. To make your own using tape (or decorate however you like), download and print out the blanks I made:

Print and cut out the cards, then align a couple strips of tape on the front and trim off the edges.
Use a 1/8" hole punch or scissors to notch the edges to keep the twine in place.
Wrap the cover with twine, tie, and write a scandalous message inside. Make mini envelopes out of coordinating paper if you're feeling ambitious!
