As a thank you for the support I'm getting on my pack, I decided to release this free ballpoint pen! It behaves like a real pen so you have to build up to your darks with pen pressure and hatching.
A couple tips for getting the most realistic results:
1. Use the brush at smaller sizes, like a real pen tip.
2. Work on the same layer to take advantage of the multiply luminescent brush blending mode. If you need to go over a dark color with a lighter color, create a new layer.
This product is only compatible with Procreate 4 and above.
