Apparatus for the alignment of plaid fabric on a cutting table includes a pair of datum elements clampable to the opposite sides of a cutting table. The datum elements each have a transverse recess defined by parallel vertical faces. Each of the datum elements has a vertical slide bar and an adjustable slide clamp member slidably mounted thereon. A fabric alignment member made of rigid transparent material includes a pair of perpendicularly arranged elements each of which is provided with a plurality of guide lines which extend parallel to the lengthwise side edges of the element. Such alignment elements may be fixed or movable relative to each other. The fabric alignment member is positionable over the plaid fabric within the recesses of the opposed datum elements and clamps the fabric in place in alignment on the cutting table.
