Last winter something broke one of my favorite bird feeders. I kept it, and in the spring smashed it up and made a mosaic of a bird with it. I knew when I made it that it wouldn’t last outside. I made no special effort to research materials, I just enjoyed smacking the thing with a hammer and gluing the pieces on a board.
I hung it from a tree in our yard and enjoyed it all summer. When I noticed a couple of pieces falling off, I took it down, scraped the tile and glue off and threw the board back in the scrap pile. A low effort, high enjoyment project.
