These were easy make using the Bon Appetit stamp set from The Rubber Café. Stamp the image on black or grey paper and emboss in white. With a circle punch, punch a hole near the top. Use you scissors to cut a "notch". This will enable you to attach it to the glass.
Using colored pencils, add details and a name. Voila! It's that easy.
Another fun idea, would be to make up several of these to have on hand and then allow your guests to write their own names.
