It’s a great improvement on shuttle tatting-quicker and a more consistent tension is achieved.
There are two active threads at anyone time (and sometimes more), the ball thread and the needle, or core, thread. The ball thread knots a series of hitches around a 15cm needle threaded with the core thread. The needle does not taper and is a consistent size from eye to tip. Different sizes of needle are used for the varying gauge of thread: the needle for this sample made from sewing thread is tiny, and very bendy, making work somewhat slower.

I wear it around the house a lot: my mother always said I had ideas above my station.
