Recommendations for scratch board beginners

[Matthew Evans]

I would say that scratchboard would be a satellite skill if not parallel to engraving. Does anyone have recommendations to start? Got inspired by a prolific designer https://m.youtube.com/c/StevenNobleIllustrations/featured. Any suggestions are welcome.

Edit: Looks like a start would be at dickblick.com or https://ampersandart.com/blog/2017/10/scratchbord-101/
