A wallcovering border includes a decorative repeating pattern which is imprinted upon a strip of wallcovering of indeterminate length and which has a substantially straight upper edge. The upper edge is applied in engagement with the corner between the wall and the ceiling to thereby permit application of the border to the wall in a substantially straight strip. A score line is embossed on the wallpaper between the decorative pattern and the upper edge. The portion of the border between the edge and the pattern is removed along the score line after the border is initially positioned on the wall to thereby provide a decorative border having a nonlinear upper edge.
