A hand operated tool is provided for attaching tufts of yarn to a canvas backing. The tool has an elongated housing at the front of which is attached a wire loop with a bight of the loop spaced forwardly of the housing and extending transversely to the longitudinal axis of the housing. A pair of clamps at the front of the housing are adapted to clamp a length of yarn which has been looped around the base of the wire loop by the operator. An elongated needle is mounted in the housing for sliding movement in alignment with the clamps and bight of the wire loop. A trigger mechanism is provided for closing the clamps about the yarn and a rearwardly extending plunger is provided for advancing the tip of the needle through the clamp and the bight of the wire loop. Optionally, a cutter and yarn guide assembly may be adjustably mounted on the housing through which the operator can feed a length of yarn preparatory to pulling it around the base of the wire loop and which operates to sever the doubled length of yarn to form a tuft of desired length.
