Zentangle Etching with Transparencies and Laser Printer - Results on Copper

The toner resist works - more work than the PnP (I'll show the PnP next) but it does work
Have not really cleaned them up but enough that I took off the resist so you can see the raised work- although I like the rustic patina look.  Now I would like a deeper etch as then I can also use them for enamelling and colouring with resin.

cleaned pieces - The transparencies work but it is more work- If I had left longer would have been a deeper etch.
