There's the kind of DIY that looks like B.A. Baracus rigged it up in the back of his van, then there's the good kind. Erik Anderson's Recycled Wine Bottle Torch is the good kind, made in classic fashion: He wanted something (patio torches) and was unhappy with the commercially available selection (have you seen Tiki torches?) so rigged something up on the cheap (using parts from the hardware store and empty glass bottles).
Anderson broke out the instructions for all to see and emulate, along with photos so pretty it looks like they were shot and framed by a pro. (Hit the link above to see 'em large.) Says Anderson,
In any of my design work, whether for clients or for myself, I'm most proud when I can find a solution that's highly creative and effective while keeping resources to a minimum. This is totally inexpensive (around $5-bucks). Plus it's a great way to recycle a bottle.
