Leclerc Fringe Twister
This is a very useful tool, and makes twisted fringe edges for scarves, rugs, and other items easy and quick to make. There are 4 clamps so that you can twist 4 groups of fringes at once.
The woodworker who makes these does a fine job, including placing felt on the bottom so that you don't worry about scratching the surface of your table. Included is a small clamp.
To use, simply clamp in yarns, rotate either direction to twist, then secure the fringe with a knot.
