I made this project because I had some extra epoxy resin left over after I made a few Christmas trees. I covered a waxed tea cap with hot glue, and I made sure there weren't any holes. Next, I poured a little bit of epoxy into it to make a layer. I then put a cutout of a painted koi. I covered it with epoxy again, and I repeated the same steps until the mold was full. I waited until it was dried, and I polished it off with toothpaste. Later, I used a micromesh sanding kit to polish it.
