I use the edging presser feet for binding and for seaming and applique. I have different widths for different projects, both left edging feet and right edging feet. I have from 1/2" down to 1/32". (1/2, 3/8, 1/4, 1/8, 1/16, and 1/32) I got mine at
Cutex Sewing Supplies They are made for industrial machines (work on high shank sewing machines) and the edging piece on them is made the same as the rest of the presser foot, not the flimsey piece of sharp metal that you find on some.
I also got a wide foot from them that I use for doing in-the-ditch. The forks of the presser foot, press down on my seam(s), keeping the ditch line open and makes staying in the ditch so easy.
