Embroidex Even Feed Walking Foot for Singer Pfaff Viking Sewing Machine (006185008-P) The Even Feed Foot also well known as a Walking Foot has its own set of feed dogs that work in conjunction with the machines feeding system to improve the flow of the fabric. This is particularly important when sewing several layers of fabric, such as in quilting. The Even Feed Foot "pulls" the top layer or layers of fabric through at the same speed as the machine's feed dogs are pulling the bottom layers or layers of fabric. The walking foot is wonderful for fabrics that stretch or slip easily, such as velvet and corduroy. You won't believe how helpful this foot is for matching plaids and other difficult patterns perfectly. Used to sew plaids, velours, velvets, ultra suede and other napped fabrics
