In cooperation with The Tolkien Shop, the largest Tolkien themed store in the world located in Leiden, Holland, I've brought some of their patches state-side in what very well may be the first ever international Tolkien Patch swap. 

The One Ring.  The first version is the traditional one ring as it looks when heated by fire or on the finger of the Dark Lord Sauron.  Primarily gold foil fabric with red embroidered elvish script.  The second version is embroidered with the Lord of the Rings title from the feature films and the fellowship in embroidered silhouette.  This patch is 2.25" tall and 4" wide with a cloth back.
