Etching metal
Chocake asked me what I use as a resist when I etch my copper, so I decided to post a picture. I have also used a fine point sharpie. I find (at least for me) that I get finer detail when I use a saline solution etch vs a muraric acid/peroxide solution etch.
PS....for some reason my iPad is posting the picture upside down....sorry
