When I use the blindstitch to sew down the back of my bindings, I do it by hand. I hide the knot first, then take a small stitch into the fabric of the quilt - and only go thru' one layer. When I come up, I slide my needle thru' the fold of the binding a short way (less than 1/4"), then come out & back thru' the quilt. "Lather, rinse, repeat" so to speak! lol :wink:
Hope this helps...
