If you've ever struggled to feed your fabric through a sewing machine, you need a Walking Foot. Also known as a "Dual Feed Foot" and "Even Feed Foot", the Walking Foot is an essential tool for any sewer. This foot has built-in feed dogs that grip your fabric for better control. Sewing thick fabric, multiple layers (quilts, binding), slippery fabric (leather, pvc, vinyl), and plush fabric (velvet, minky, suede) is fast, easy, and professional. To use this foot on Elna 5000, 6000, 7000 (with a grey lifter lever), you must change to white lifter lever #461201-10.
