If you get the same mushrooms that I did, that have floral wire in the bottom, pull out the wire and use rough sandpaper to make the mushroom stem flat. Also, sand a bit off the back so the mushroom can lay flat. Spray the mushrooms with resin spray sealer.

Spray the jewelry mold with mold release. This mold shape fits 3 mushrooms nicely in a row - use other mold cavities if you want to play with different designs.

Let the mold release dry while you mix up some resin. While wearing gloves, pour 10 mL each of sides A and B (for a total of 20 mL) into a mixing cup and stir for 4 minutes or until there are no swirls visible.

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.

I did a couple of coats of spray sealer to add some shine back to the resin after it came out of the mold.

When the sealer completely dries, attach a clip with e6000. Be sure to not glue the clip closed! (Clip around a silicone mat if needed.) Also, remember to glue them on like they were a pair - one going each direction.
