I have a bunch of 3/4 wide nylon strap webbing and D-rings to attach to the ends of them.  Typical put through D-ring about  1 1/2 and sew a box pattern to secure the ring to the strap webbing.  These are going on some duffle bags to help secure them and to use shoulder straps if needed. How does one get the machine to do this?  The sewing machine's drive feet don't like the nylon webbing strap material as it is fairly open weave so the stitches come out all messed up (lots of tangles and lousy thread pattern). Does one do it as a freehand stitch on the machine?  I thought about the zipper foot to get close to the D-ring part, but the rest is a mess and having not that much material to catch is frustrating. Thanks. B~
