Paint wood heart
Paint the front of the wood heart red and let it dry completely.
Paint the sides
Paint the sides and back of the wood heart. Let them dry completely.
Paint the corks
Paint the sides and tops of 60 to 70 corks (the amount of corks needed will vary depending on the size of the corks). Let them dry completely.
Glue corks in place
Hot glue the corks in place starting with a single, vertical row down the center of the heart. Hot glue corks around the sides of the heart, then fill in the remaining empty spaces with more corks. Towards the end you may have to squeeze a few of the corks in to fit tightly.
Hot glue 1 or 2 magnets to the back of the wood heart and place it on your fridge.
