I just spotted those painted fence posts, too. They're great! You know what else you could do with them, is to attach a broad base, put another board on top, and use them for plant stands. A friend once made me some stands for my stereo speakers that way. You'd probably have to use wooden 4x4 for that, tho, not the plastic ones. Hmmm, or you could drill a hole in the bottom of the 4x4 and stick it over a piece of thick rebar sunk into the ground.
