Part 3 of Electroetching - Preparing metal for the electro bath & using Tuck Tape as a Resist 

Preparing your metal for the etching bath. Protecting the back and exposed edges of metal. How to hang the metal package. Plus a bonus, brand new, first time I ever figured it out,....using the stickiness of Tuck Tape and paper punches to create resist patterns, VERY COOL! Be sure to sandwich tape between two layers of parchment paper to prevent it from gumming up the punch.
