A dulling assembly includes a corrugated bundle having a plurality of generally vertically oriented planar paperboard sheets with fluted paperboard sheets located therebetween, each fluted paperboard sheet being adhered to the two planar paperboard sheets it is located between, and a plurality of grains of sand adhered with glue to a top surface of the corrugated bundle. A method of creating a dulling assembly includes the steps of providing a corrugated bundle, applying glue to a top surface of the corrugated bundle and applying sand to the top surface of the corrugated bundle.
