i've heard that it is not that easy to use. when doing total machine binding, i sew the 2.25" binding to the back first. then i use my joining foot and move the needle 5 clicks to the right.... that way, i can follow the binding edge on the front by butting it up to the binding and the needle sews an even distance from the edge. this is for every day quilts. for special or show quilts, i sew to the front and hand sew to the back.
