The back-up pad includes a support member and an engaging means provided on a major surface of the support member for releasably engaging the hooking stems of the abrasive article. The engaging means includes a substrate having a first surface, a second surface, a plurality of loops projecting from the first surface, and an adhesive applied to the second surface. The plurality of loops comprise a continuous strand, the strand including a plurality of loop portions projecting through the substrate from the second side to the first side to thereby form the loops, and a plurality of connecting portions between the loop portions. The substrate is located between the loop portions and connection portions of the strand, and the adhesive adheres the connecting portions of the strand to the second surface of the substrate. Also disclosed is an engaging means for use with a back-up pad, and a method of stitching the engaging means.
