Glue corks in place
Using 30 to 40 corks, hot glue the corks in place starting with a single vertical row down the center of the heart. Continue hot gluing corks around the sides of the heart, then fill in the remaining empty spaces with more corks.
Apply Mod Podge
Paint the top of the corks with Mod Podge. While still wet, very carefully take a piece of gold leaf and lay it on top of the Mod Podged corks. Alternate this process between both the silver and gold foil.
Once the gold and silver leaf is in place, press it down with your fingers or the rounded end of your paint brush to set it into place. Repeat until the top of each cork is covered.
Hot glue 1 or 2 magnets to the back of the wood heart.
