A tape is woven on-grain and has printed thereon at repetitive intervals an optically converging marking pattern which converges onto a locating pattern. The converging patterns are most preferably lines which resemble the mathematical symbols for "greater-than" and "less-than". The converging patterns each converge on opposite sides of a rectangular box which designates where a board or other structural component will most preferably be located. Within the rectangular box is an additional line which subdivides the box equally into two parts and which contains at its center a small diamond The diamond identifies the geometric center of the structural component, for nailing or other purposes. The subdividing line may also be used in combination with the two converging patterns to locate two structural components, side-by-side. In this latter case, the two converging patterns each converge in with the rectangular box at the respective geometric centers of the two structural components.
