tying down

One of the steps employed in working headbands. The thread used in forming the headband is taken down the spine to a point beneath the kettle stitch and then back up to be wound around the core of the headband once again. The purpose is to anchor the headband solidly to the spine. In the early days of headbanding, tying down was done in the center of each section; today, however, it is usually done at every three or four sections and even then not always in the center. (236 )
