Had an old leaky pair of neopreme waders and four old bar stools from work, a little cutting and stapling, and tada, waterproof bar stools.

My latest off tIme project was a bourbon barrel converted to chair. Barrel was a used free bbl from work, and about $10 of misc materials.

I always throw a huge superbowl party in the garage/mancave so I have lots of seating, big screen tv, stereo, kegerator and beer fridge.
What you got kickin around the garage?
