I use a zipper foot when doing my binding.
I cut 2.5" WOF strips, join on the diagonal. I then use my 1/4inch foot to sew my binding to the back of the quilt. Fold binding to the front, change to my zipper foot and sew it to the front. I get an excellent result, that is sturdy and find that I don't 'slip' off the binding when I use the zipper foot to attach it.
