Are you hosting Thanksgiving this year? If you are still in need of a cute idea for place cards, maybe give this one a shot.
It's super easy, although you will want to be VERY careful. Simply make a slit in a cork with a box-cutter or exacto-knife. I found it helpful to make a very shallow cut initially and then dig deeper to make the groove both deeper and slightly wider.
To prop them up, you can glue them to something heavy-ish and flat, or just do what I did:
Two tacks pushed in the back at a slight angle will keep your guests from rolling around your table while you're trying to feast.
Voila! This project took me about 30 minutes max. Let's eat!
