Folded Ruling pen with Kerri Forster

I took a live class with Kerri Forster - Folded Ruling  Pen this past weekend. The last time I took a class with Kerri using this tool was in  2016
This is the best of what I did this past weekend... sigh and that's saying a lot. I seem to have digressed in the past 8 years.

On Canson XL Pen & Ink paper using my funky mix of Holbien gouache paints and either Tim's folded pen or a basic folded pen.
