Brush a generous coat of clear drying sealer to the inside surfaces of the wood plaque.
While the glue/sealer is still wet, gently place the pressed fern fronds onto the surface. Press down the fern fronds onto the glue. Let dry completely (ideally overnight).
Mix exactly equal amounts of Resin and Hardener into one measuring cup. The size of your piece will determine how much resin you need.
Stir continuously for 2 minutes, scraping the sides of the container.
Pour the mixture into a second cup and stir for an additional minute, scraping the sides of the container and stir stick.
Slowly pour the resin mixture over the ferns.
Tilt the plaque to get the resin over the entire surface. The resin will settle and level itself out over time.
Cover to keep dust from settling in. Ensure your tray is placed on a level surface. After about 15 minutes, remove any bubbles that have risen to the surface by gently blowing over the piece through a straw. Use a clean toothpick to release any larger bubbles.
Cover and allow to cure overnight (will fully cure over 72 hours).
