Abstract: A template for marking golf balls with identifying indicia includes an elongated, rectangular-shaped main body member which is foldable into a cylinder for encompassing the golf ball, a central body portion having a plurality of apertures in the form of letters, numbers, and other symbols arranged thereon, a first end having a flexible tongue formed from a U-shaped slot, and a second end having a transverse slot. When the main body member is rolled into a cylinder for receiving a golf ball for marking, the tongue is inserted through the slot for maintaining the cylindrical form, whereupon the point of a pen can be successively inserted through the appropriate apertures on the central body portion in order to mark the golf ball with an identifying name, symbol, expression, monogram or moniker.
