Fancy some big, glowing letters? Adrian Giddings linked to the Character website on Twitter (also via Design Observer), who refurbish and sell old letters from signs. They’re rain-proof and illuminated with LEDs, so I’d guess they’re good for the garden and will last quite a long time. I quite fancy a garden illuminated with big letters dotted about in the foliage. Mind, if you’re after the post-industrial look, the site’s home page has some lovely photos of some of the letters in dark and moody settings for your inspiration.
