I like to etch some glass as well
I take the stamp pad that is a resist and stamp onto the dicroic piece I will be fusing
then put a covering of etching cream on the piece - this can be tricky as some dichro takes seconds others a minute or two to etch into the dichro.
But you can bet I'll be doing some of the zentangle stamps this weekend and etching them onto the Dichro and fusing them. Should be interesting
