So you have a budget of about $0 and you don’t want mud on your jacket, what do you do? Well, by using an old corrugated plastic sign and some zip ties you can make a really simple bike fender. OK, it may not be the prettiest fender I’ve seen, but it still has a lot of charm in its simplicity.

    there should be a site dedicated to things you can make out of old “for sale” signs. Wind generator, model boat, automata, bike fender…

    plastic rain gutters work great too. home depot/lowes – for a few dollars, make them for yourself and friends! ;-)

    Plenty of them up the street, been there for 4+ years, doubtful that the houses are really saleable, and the signs are starting to fade.
