These are kind of brilliant. I ran across them on Orange and Black, and a bit of sleuthing revealed that they were part of an ad campaign in Romania. Guinness is a niche brand there, and the coasters were created as a low-cost idea to drive sales on Halloween.

These would be a fun and not-too-terribly-difficult project if you’re handy with an X-Acto knife. The coasters could be cut out of acetate or other thin plastic, or possibly fron thin sheets of cork; if they won’t be used heavily they might also be cut from sturdy felt.

A set of these coasters would be an interesting hostess gift, particularly if paired with a six-pack of Guinness or a dark alcohol like Blavod. For a simple idea, they have an enormous amount of style.
