Abstract From the Canadian patent
A camouflage sheet is perforated in such a way that the perforations produce or contribute to the camouflaging effect. The holes which together form the perforations are arranged in positions corresponding to the points in a triangular raster or matrix, so that three adjacent holes form the vertices of an equilateral triangle. The edge portions of known sheets for camouflage in monotonous terrain, e.g. fields desert, snow, lakes or the sea may be provided with the above-mentioned perforations in such a way that the perforations become sparser from the edge of the sheet towards the center.
