The Walking / Even Presser Foot from Singer is perfect for sewing several layers of fabric together. This foot is commonly used for quilting. The walking or even foot walks effortlessly through layers of fabrics. This is because the foot has its own set of feed dogs that work in conjunction with the machine's feeding system. The upper feeding mechanism "pulls" the top fabric at the same rate that the machine's feed dogs are pulling the bottom fabric. This helps to keep the layers together, prevents shifting and bunching of the top layer. The Walking or Even Feed Foot is also great for matching plaids or stripes and sewing with nap or pile.
