HI Guys,
The legs are actually Dyed blue pheasant tail!!
As for tips on tying legs.The only thing I can think of is when I pull two fibres of the tail stock, I try to leave a burr of the stock on the butts of the tail fibres, so they are both still joinned together, then I just tie a knot using both tail fibres, but hold the tips stationary and tighten from the end with the burr on.That way the Knot travels up the fibre and the gets closer to the tip of the fibre.
Does that make sense????
