The weaver’s knot rolls nicely off the thumb. After a little practice.
Tying in is not for the un-nimble of finger (or weak of back).
There are two warp yarns in every dent. Except on the selvedge which has three in each of the first four making twelve. Then there’s a gap of five dents followed by the leno (two of) .
Then comes the tweed.
Go right to left, keeping a grip with the left and tying with the right.
The plain twill draft is a doddle. Except when you have to change from a herring bone.
