"Does anyone here use collage techniques to make beads/jewelry?"
I do too, in the 80s I did a polymer clay pendant design where I made a clay frame over a piece of sheet metal then added the images and epoxy over. Made wall hangings that way too. I have collaged wood beads using gel medium and varnishing, lately I have got ahold of some 30x40 glass cabs and am adding a picture beneath them for seed beading. Since I'm not using multiple images there it's more decoupage than collage but it does use a picture in jewelry.
I made a huge wall collage with a mermaid theme, it's under glass and has a rainbow patina copper sheet metal border, that's up in my hall (made in the 80s also). My mom collaged our whole bathroom in the 70s when I was a kid, I wish I had pictures of that, it was great!
