Unbalanced Twills

Unbalanced twills are those where one side of the fabric shows more warp, while the other

shows more weft; this is in contrast to a balanced 2/2 twill. On four shaft, a 1/3 twill is

unbalanced. On the left is the drawdown

showing the weft-dominant side.

On the right is the corresponding weft-

dominant side of the fabric, with the

reverse, warp-dominant side below.

Shown in the drawdown below is how to

weave both weft and warp-dominant on

one side of the fabric. Three shafts have to

be raised for the warp dominant fabric, so a

total of eight treadles are needed.

Since most four-shaft looms have six, th3 skeleton tie-up

in the drawdown on the left can be used.
