Unlike the surface couching, where the couching thread sits on the surface of the fabric, the underside couching technique allows it to pass through the fabric and hide under the fabric.
Visually, it might end up looking like the backstitch. Now, underside couching was used during medieval times in Ecclesiastical embroidery or church embroidery, where metallic threads were used often. Since it was tricky to pull the metallic threads in and out of the fabric, it was probably much easier to couch it down and hide the couching thread on the reverse of the fabric. The technique is pretty much similar to what a machine does when stitching.
This stitch can be used to fill up portions of the pattern, as it was used to in various medieval embroideries. I will use simple cotton floss to illustrate this stitch, and work over a curved line to show how easily this stitch can meander.
