Fenceposts rot before the exposed wood rots. Lucky for Layout, over on Instructables, that his wife is so resourceful. She's the one who suggested that this pile of still useable wood be turned into a rustic outdoor table.
Coincidentally, the list of materials he needed for the table was exactly what he had left over from the gate.
4x4 posts approx 6ft long (4)
4x2 rails approx 3ft (2)
Palings (enough to cover a 6ft x 3ft surface)
