Follow the packaging instructions and mix up the first layer of resin. Mix exactly equal amounts of Resin and Hardener into one measuring cup. Stir continuously for 2 minutes, scraping the sides of the container. Pour the mixture into a second cup and stir for an additional minute (use a new stir stick). Scrape the sides of the container as you mix.
Pour some silver craft glitter into the resin mixture and combine thoroughly.
Distribute the glittering resin mixture evenly between the molds, to about 1/8″ thick.
Set the pieces on a level surface and cover to prevent dust from falling in. After about 15 minutes, remove any bubbles that have risen to the surface by gently blowing over the ornaments through a straw or using a small kitchen torch.
After about 3 hours test the firmness of the resin by gently touching the center. You want the resin to be firm, yet still tacky so that you can layer on your sealer images. Center the image in the mold and let cure for a couple more hours.
At this point you can lay on any other embellishments, such as the date. Use a multipurpose sealer to seal it in place.
