These metal letters from
Urban Outfitters are fantastic. They are quite large at 6 x 10 x 1" and are available in some cool colours for only $14 each + postage. The have a built-in bracket on the reverse for hanging and the website says they come in different styles, although there is only one style shown.
Now I can find them on the US website, but not on the
Uk site?? So maybe they are only available in Uk stores and not online?
