Just experimenting with trying to make my lines look kinda blobby like I'd used too much ink and it bled and pooled together in corners and intersections. IDK how much I'll use this, but it's fun to experiment anyway. :D

A binarize or threshold filter (name varies by software, but they're the same thing) converts your image to pure black and white with no shades of gray, and I used it to get the smoothness of a soft/blurry brush without the actual blurriness. :D
