The Schmetz Stretch Twin Needle features two Stretch Needles connected to a flat shank via a bar, for simultaneous sewing of two parallel seams. The stretch needles have a medium ball point, smaller eye, and a deep scarf. The unique design of the scarf and eye prevents skipped stitches and the ball point tip helps to prevent thread damage and holes. The Universal Twin Needle can be used with all conventional household sewing machines with a zigzag function. (Verify the machine throat plate can accommodate needle width).
