An implement holder to be attached to a cap or hat is provided. The holder is designed to be affixed to the side portion of the cap proximal the edge. The holder is an integral unit including a first leg, second leg and third leg. The first leg and the second leg are interconnected to form a first jaw or clamp, the first leg to be received between the cap and the head and the second leg to remain outside and flush to the cap. The first leg is resilient and includes means to maintain attachment to the cap. The side of the cap is placed intermediate the first leg and the second leg. The third leg and second leg are interconnected and form a second jaw or clamp which has the general shape of an U-shaped channel. The U-shaped channel is generally parallel to the cap when the holder is affixed thereto. The channel includes a plurality of longitudinal ridges located on the interior channel walls of the third leg and second leg. The second jaw may receive a pencil, pen or other elongated implement. The small ridges help retain the pencil, pen or other elongated implement in positive relation within the second jaw. The third leg is also resilient and imparts a retaining force on the instrument being retained in the channel. The outer wall of the third leg is smooth and is designed to receive identifying or advertising indicia. The holder may also be affixed to the temple of eyewear, including glasses, sunglasses, or protective eyegear.
