Our dearest friend Debbie, just returned from a wee excursion to the current mecca of all things cool, New York and returned with this adorable little purchased from the Brooklyn Flea Markets. After a bit of google/etsy ferreting, it seems there are a few people offering a similar product albeit without the market/NY experience. One of the nicest we found was by Ms Thomson. It has an adjustable silver band and can be purchased in the letter of your choice.  A splendid preset idea we say.
