I really, really, love this idea of house numbers as a sculptural element. $185 per digit from curranonline.com. I don't have an idea for making these suckers, but I'm open to suggestions!
Vinyl house numbers. Vinyl is NOT expensive to get custom-cut from a sign shop — and if you're really feeling lazy you can totally get the sign shop to come install your new address, too. You could do any font, any size — it's a super flexible medium.
Making threaded house numbers is simple, but looks complex. The thread might get ookie after a while, but then you just take it down and re-thread. Ooh! Ooh! OR you could use this rad fluorescent twine! Here's how you make these house numbers.
Have a front porch? Make throw pillows with your address on them and multitask!

Speaking of eco-friendly, nature-lovers will adore these twig house numbers!
