For guests who brought cards, I created a place to leave them. Using a vintage suitcase that I found for a few dollars at an estate sale, I lined the inside with vintage flocked wallpaper (also found in my treasure-hunting travels). I attached the wedding invitation and made a stamped tag. All of this accompanies a moss-covered letter that I created using a papier-mâché letter, sheet moss and spray adhesive. Creating this accessory cost around $10.There are many ways to customize this idea. Try using a big wire or natural basket and filling it with a cushion of pretty fabric.
