Knotless thead drive not difficult if you know what you are doing. Sorry about the pun.
I used Japanese embroidery silk which worked quite well by thread drive standards but is so far behind the state of the art that I dropped it as a commercial proposition. The fun part was that a huge range of colours is available - I used red, green and yellow and called it natty thread (with apologies to the late Bob Marley).
