Recent experiments using aluminum foil tape as plates for etching. The idea came from https://www.handprinted.co.uk/ramblings/aluminium-foil-tape-printing
The technique is very simple, and the plates created with plants and leaves will not last forever. I am still in the very early stages of this technique, but see potential.
The tape I used may be a little thick, so I am going to try to find thinner. I feel there is more detail that could come through.
