I have used this method for many years, but I add an extra back support by using either those clear plastic buttons, or the itty bitty buttons, both of which need to have two holes. I stitch the first entry of thread into the fabric, then when the thread exits on the other end THAT is where I slip the thread through the first button. I attach the second small button when I exit after the second pass. Depending on the fabric thickness there have been times that I make a third pass of the base thread before I begin the "knitted" (as I call them) stitches on the right/loop side. Each time I exit the base threads I attach the thread to the buttons, almost as if I am sewing the buttons on to the fabric. It ends up with the loop on the right side of the garment and being supported by the buttons on the wrong side of the garment.
