Hi! I am trying to compile info on how to use seashells and glass pieces in resin on clear glass windows, starting with a small project of course. I see beautiful art pieces that include small crushed/broken glass to fill in spaces around seashells and focal points but can find absolutely no instruction on adhering this glass “gravel’. Is it mixed with resin and poured on? It can’t be possible that each small piece is glued on separately?? Any info you can give would be greatly appreciated! Or, a shove in the right direction. Thanks!!!
