Hi @sketchinbad, I use a Pogo Connect. You should take a look at @mademistakes “Mastering Paper" series. It has a ton of useful tips on how to get realistic effects with Paper.
The Pogo has pressure sensitivity, but everything I’ve drawn should be possible with any stylus, or even a finger. One of the best tips is to not lift your stylus when you’re using the watercolor tool. That way you get a smooth tone. I just vary the speed: slow to color in an area, or fast when I want to shade something or “blend” the colors.
