Abstract
A vertically elongated column, either square or round in cross section, is covered by tightly wound rope which is wound in a helix around the column and is affixed thereto by glue and recessed nails. The column extends upwardly from a horizontal base. The rope is densely wrapped around the column so that none of the column surface is visible between adjacent loops of the rope.
