I'm a lazy/low-energy artist, and I prefer having a messier style. Not only does it save me motivation, but it also gives texture to my art! If you have the same habits as me, or you're just simply looking for brushes, feel free to experiment with this one!

Acts like a slightly dry whiteboard marker.
But, If you prefer a smoother application, I recommend altering the settings within the "Ink" subsection of the brush.
The default settings are shown in the picture below.

The brush size will differ based on your velocity and pen pressure.
In my opinion, this brush works well for most tasks, but it was made with initial sketching and line work in mind.
