Shoptalk—deciphering architectural and historic preservation jargon one word at a time!
a masonry finish that gives the appearance of a band at the edge of a stone, typically one inch or more in width (Source: International Text Book Company, International Library of Technology 31D, 1923)
In traditional stone cutting margins, also called drafts, were used to layout the face of the stone and square it for installation in the wall. In softer stones, such as limestone, the margin is typically hand tooled with a chisel and mallet to create parallel fluted grooves in the stone. Modern machine cut tooling tends to be square in profile rather than fluted and lacks the slight irregularities of handwork that makes it pleasing to the eye.
