I am a free motion quilter and I absolutely love this presser foot! I choose this over the BSR.
Came quickly and fit my machine. Just what I ordered. Thank you
Happy with my purchase.

The bernette Zipper foot for the b33 or b35 has a narrow shape, allowing for the ease of stitching on zippers. The fabric is fed evenly while you can sew along the zipper coil very closely. Attach the Zipper presser foot in the right or left position, depending on which side of the zipper you choose to sew in. To sew the left side of the zipper, attach the zipper foot on the right-hand side of the pin. To sew the right side of the zipper, attach the foot with the left-hand side of the pin.
For b33 and b35 sewing machines.
