When I was recently given a letterpress H necklace, it brought tears to my eyes. What an appropriate and lovely gift! What I really like about it is that when it's hanging, a casual observer doesn't really know what it is. So, wearing the necklace is kind of like wearing a fun little secret.
In addition to these necklaces, Gwen Delicious offers jewelry made out of typewriter keys and many other goodies. Wouldn't cuff links with your first initials be a great gift to a groom on your wedding day?
