I've done it a lot and it's very easy to do. Basically you hand-wind your bobbin with your yarn/thread/cord/etc, put in so it does NOT go thru the tension then stitch your fabri from the wrong side. you can do fancy stitches, alto simple is better...I've used various sizes of zigzags, etc, but even straight stitching comes out looking good.
It's easier to do on a top-load or drop-in bobbin than on a front-load bobbin.
I've used metallic threads, hand embroidery threads, silk ribbon, light yarns, etc.
