The topmost cloth was the fair linen, a long white linen cloth laid over the two linen cloths. It had the same depth as the mensa of the altar, but was longer, generally hanging over the edges to within a few inches of the floor or, according to some authorities, it should hang 18 inches over the ends of the mensa. On an altar without antependium and consisting of the mensa resting on columns or made after the fashion of a tomb the topmost linen did not have to overhang the edges at the sides. It could be trimmed with lace on the ends and could be ornamented with figures of chalices, hosts and the like. Five small crosses might be embroidered on the fair linen - one to fall at each corner of the mensa, and one in the middle of the front edge. These symbolised the five wounds of Jesus. The fair linen should be left on the altar at all times. When removed for replacement, it should be rolled, not folded. It symbolized the shroud in which Jesus was wrapped for burial.
