Since I am now using my home base for teaching, I decided to respond to some requests to teach scratchboard and the engraving idea behind it. Although it is not engraved in metal, it offers the very same challenges.
One remarkable quality is that doing large scratchboard is very time consuming and difficult, the opposite is true when in comes to graphic digital reproductions.
This is one of my scratchboard drawings enlarged, which I feel loses zero impact, considering how affordable it is and how it can be applied to metal as well as textile. Click the picture to purchase.
