I did this technique years ago with my kids. One of my sons actually won first place in the fall fair with his foil art. Pretty cool. My friends created these a while ago. I just found the camera, thankfully. We glued down some string, covered that with foil and then added layers of acrylic paint. These make great journal covers. Oh yes, I also put a coat of varnish over it all once it had dried for a few days.
