Heddled

[…]all reproduced in Ananda Coomaraswamy's Medieval Sinhalese Art are ordinary twill weaves which are produced with little effort on a multi-heddled handloom.

It is difficult to decide with von Stokar, that such twills were woven on a four-heddled loom (6).

Necessary and productive as a many-heddled loom is, there is something basic and satisfying about covering each warp thread by hand, in a tapestry or needle technique.
