The thread guide, with two open deflection stirrups to lead the thread to the needle of a sewing machine, is single coiled round wire to form the guide to give a cylindrical opening. Both ends of the wire are each bent round to form circular thread guide eyelets. Radially extending deflection stirrups are located on each side of the central opening. ADVANTAGE - The guide allows different threads to be fed separately to the needle.
