Abstract
Abstract A wallcovering material having a paper backing being color and/or design printed face to which substantially parallel warp and fill yarns are tricot stitched thereto to provide an aesthetic structure through which the color and/or design shows through. The warp and weft yarns are knit to the paper backing material and held firmly in place by the polyethylene film on the face of the paper backing. The warp and weft yarns are openly spaced so that the color and/or design printed on the paper shows through and provides a pleasant view to the area in which the wallcovering is installed.
