The Free-motion Echo Quilting foot is designed to give you more control when free-motion quilting. The large base ensures good surface contact with the fabric and provides better control of the stitching. The transparent base allows for 360 degree visibility. Vertical, horizontal and circular markings on the foot make it easy to follow a continuous line quilting pattern or design on the fabric. Sew straight lines or follow patterns with rounded edges in any direction. Compatible with machines in Groups B, C, D, E, F, G, J, K.
