yup agree w/all above...can't live w/o my walking foot...I have one for all of my machines...Vintage Singers, New Singers, Husq Vikings. First thing I search out when I pick up a machine. I found by not having one and trying to quilt I'd get fabric bunch up on the back and then I'd have to pull out stitching ...once I got that walking foot no more issue.
I use it for binding, applique, quilting line by line or echo's anything layered.
