Here’s How:
Step 1
Use a pencil to trace the shape of your agate print on the cardboard. Make sure to cut your carboard over the shape that you have. 2 pieces or cardboard are needed for each print.
Step 2
With your tape, start taping the 2 cardboards together going around and over it until they are enitrely covered with tape.
Step 3
Once the cardboards are covered up, you can now start painting them with gold spray paint.
Step 4
Spray a little glue to the back of the prints to stick them into the painted cardboard.
Step 5
To make them water-proof, apply a thin layer of mod podge onto the surface of the agate print using your fingers. Let them dry for a couple of hours.
And your agate coasters are done!
