Total /beg/ here, I’ve never been too deep into animation and was curious on line work while animating. I’ve always been under the assumption that all lines have to have the same line weight because obviously it would be difficult to constantly replicate tapered lines over and over again. I saw the digievolution clips from Digimon Adventure Tri and they managed to do varied line weight, as you can see the liens taper frequnetly although granted it’s used scarcely throughout the series and is only really there on closeups. So is it possible or not? Or is it only possible for level 100 animators and beginners shouldn’t even attempt it?
