I actually use a line tool! Since I use a mouse, I canāt get proper pressure to work when doing the lines, so theyād end up looking really messy and squiggly. The line tool that Paint.net has is really practical, because it gives you two options; one where the curve points are more…ādirectā and one where the curve points make the curve smoother (I use the second one the most to make the smooth lines)
Itās hard sometimes to get it right, since Iām not the best with poses, but I prefer it more than I would using the normal drawing tool (which I use more for doodles)!
