I JUST BOUGHT A BIAS BINDER FOOT FOR MY MACHINE AND IT WORKS GREAT. HOWEVER, NOT FOR REALLY PUFFY QUILTS AS I DON'T THINK IT WOULD FIT. THIS FOOT WORKS FOR THE THINEST BATTING WHEN YOU MAKE PLACEMATS. SEW AROUND JUST ONCE, FRONT AND BACK BOTH GET CAUGHT IN THE SAME LINE OF STITCHING. YOU CAN USE A DECORATIVE STITCH IF YOU WANT. MY FOOT IS ADJUSTABLE FOR DIFFERENT WIDTHS OF BINDING.
