Fringing a fly plaid

[gilmore]

Hi folks!
A couple people have asked how to make the kind of purled fringe on the edge of a fly plaid like the one shown on the following site:

Select 4-8 warp ends (depending on the weight of the yarn) For the kilt fabric, I think that 6 would be about right. Anyway try 6 and see how it works. Divide the six into 2 equal groups. Twist one group of 3 to the right until it kinks. Holding on to the end of that, twist the other three to the right until it kinks. Hold both together at the tip and twist them to the left until the whole group of 6 kinks. Tie a tight overhand knot in the end...

Do you mean an overhand knot or a square knot?
