Step One:
Next time to you go to Urban Outfitters, save your clothing tags. I have always admired the out of focus, dreamy quality of the pictures printed on the tags.
Grab your scissors, a bit of string, Sharpies, glue stick, and some heavy stock paper.
Cut the stock the same measurements as the tag, adhering securely.
Add your message or image on the back. I simply write, "Ashley's Bookmark." Simple is good, simple is our friend.
Poke the card stock based on the existing hole of the tag. Pull a string through the hole, and tie luggage tag style.
Enjoy and admire the loveliness of your kept page. P.S. friends and family be expecting one of these lovelies in the immediate future!
