Phat Dyes dvd (
http://www.phatdyes.com/) uses artificial sinew like M. Fowler uses string.
He winds the sinew around many times in his ties; he also doesn't really tie off and ties dry/soda soaked too.
His tied pieces look very sturdy; he also ties really tightly.
I tie that way sometimes, but on wet/damp pieces - the waxed sinew has a tendency to stick to itself when wrapped numerous times.
I have gotten to the point that I feel some tying materials tie certain types of ties (and fabrics) better than other others.
For example, I've started to use rubber bands on spirals; it seems the easiest.
Another example is on long ties like ecilA's rainbow shirt (
http://itiedye.com/smf/index.php/topic,709.0.html), I like to use sinew like Tom&Martine. Tying a long piece is annoying (and the piece tends to twist) when using a continuous "thread".
