I follow mostly the same process as Tartan and roguequilter. Although I don't stress about how much batting I might be picking up. What I also do, though, is 'lock' each stitch. Not a ladder stitch per se, but close, but each stitch ends up being 'knotted' to a degree. I come up through the backing/binding and go under the loose thread from the previous stitch and pull until it is taut. Sort of 'knots' each stitch and to the best of my knowledge, none of bindings have come apart yet. I usually catch 3-4 threads of both backing/binding on each stitch.
