Should a weaver take into account clean cut lines in other weave structures besides 1-3 vs 3-1 twill? For instance, should one weave clean cut lines when weaving turn twill?
Clean cut lines are important in turned twill. In Season 5 E1 I go over all of that but in S6 E1 I break the rules :)
Have a look at those episodes and you will see all kinds of examples of clean and not clean.
