You will need:

–  Coaster mold

–  Resin – I used Easy Cast, but Envirotex Lite works well too.

–  Cello glitter – blue and white (available at Michaels and Hobby Lobby)

–  Clear Mod Podge

–  Picture of a shark, sized and cut out

–  Nail polish – light pearly blue and white (optional and acrylic paint could be substituted)

–  India ink or resin dye
