Abstract: A golf training device including flat, web material having a transverse dimension of about 1/2 to 3 feet, and a single internal target hole having a diameter of about 4 1/4 inches. The softness, flexibility and thinness of the web material is such that, with the web material placed on a holeless surface, a golf ball rolling thereto by a putting stroke, will be only slightly impeded by both the peripheral boundary of the web material, and the circumferential boundary of the target hole.
