A marking device is disclosed to enable the placement of an indicator mark on one side of a sheet of material to mark the approximate periphery of a stationary object. The device consists of a base containing multiple marking members with a marking surface raised above the base surface. A contact plate, portions of which extend above the base surface, is connected to the base through the use of a pair of opposing connectors. The contact plate extends from the base a distance sufficient to prevent the sheet material from contacting the marking members without the application of sufficient pressure to compress the contact plate.
