Abstract: A golf putting aid comprising first and second golf balls connected together in an abutting relationship by a threaded connector that extends into holes formed in the first and second golf balls. The first golf ball includes a center formed by a thin wall, an elastic cover wound around the thin wall, a hard cover enclosing the center and elastic cover, wherein the hole formed in the ball extends through the hard cover and terminates adjacent the center. The second golf ball also comprises a center formed by a thin wall, an elastic cover wound around the thin wall, a hard cover enclosing the center and elastic cover, wherein the hole formed in the ball extends through the hard cover and terminates adjacent the center. The threaded connector has first and second threaded ends extending into the holes and urges the first ball to abut the second ball, such that centers of the first and second golf balls are spaced apart a distance less than the length of the face of the putter.
