Although I sometimes tire of getting into a dinghy stuffed with old buoys, logs(yes, logs!) and other flotsam, I think it's just as well buoys and pot warp(both will last ions in nature) find some other use rather than becoming part of the wild Ragosa bushes on Maine islands.

Here's a buoy chandelier in our house over some stairs(the elec. recp is wired into the stairway lights).

EAsy to make, all you need is a string of Xmas lights and a hook in the ceiling.
