ABSTRACT:
A wave-form carpet layer's template used for cutting the edges of pieces of carpeting in matching wave-form patterns preliminary to sewing the side edges together in a substantially invisible seam. The template comprises a flat, rigid strip of structural material having two legs arranged substantially at right angles to each other. The inner and outer side edges of both legs have uniform wave-form contour, the crests of the inner side edges being opposite the valleys of the outer side edges. The width of each leg is substantially equal to one-half the wave length of the wave-form contour. The apex of the two meeting outside edges is located in the crest portion of one of the side edges and the valley portion of the other of the side edges.
