Set the mushrooms, flat side up, into the resin. Add a bit more resin to almost cover the mushrooms.
Remove bubbles again, and adjust the position of the mushrooms if needed as the resin starts to set.
After about 4 hours prepare more resin (about 12 mL total this time) and add gold/green Color Creator chunky glitter. Then pour a layer over the mushrooms.
Demold after 24 hours. I find that pressing from the back of the mold helps the pieces pop out.
