For napkin ring, cut a 3-inch piece of ribbon, form loop, and hot-glue ends together. This can be sized to any napkin. We chose to use velvet ribbon but this technique works with other thick ribbons. Try patterned, metallic, or silk ribbons.
For bow tie, cut 8 inches of ribbon, form loop, flatten, and hot-glue ends together. Cut a little over 3 inches of ribbon (to allow for slight overlap) for center of bow tie. Pinch flattened loop loosely in middle, wrap cut ribbon around it, and hot-glue ends together in back. Hot-glue bow tie to napkin ring.
