The ditch foot I use to sew the back binding on. The walking foot is a must for quilting straight lines through the three layers of a quilt.
It feeds the quilt layers evenly.
The ditch foot wont even feed so its not so good for quilting. But it sure does keep your stitchs in the ditch for sewing the binding to the back of the quilt by sewing in the ditch on the front.
