Clean your coaster molds under hot water with dish soap and let air dry.
Layout your workstation with scrap paper to protect the surface.
Use your coasters as a guide and lay out your pressed flower design. Take a picture for reference and set flowers aside.
Wear your gloves while working with resin. Follow the instructions on your resin to combine parts A and B in a disposable cup. Mix together well with a popsicle stick for five minutes until there are no swirls.
Pour half your mixture into the coaster mold. Place your pressed flowers in the mold and then pour the other half of the resin over top.
Use a popsicle to help move your flowers back into place. Add crushed gold flakes, once again using the popsicle stick to move them around.
Use a butane torch to go over the coasters to help eliminate any bubbles.
Move your coasters somewhere safe to cure for 24 hours.
To clean up, dispose of anything with resin on it as it will harden. Use isopropyl alcohol to clean up resin such as surfaces and the measuring cup.
After 24 hours, pop your coaster out from its mold. Enjoy!
