Place small pieces of wax into the spoon and melt over a tealight. Using a toothpick will allow you to thoroughly blend multiple colours. Once the wax is melted, pour onto a letter (or other desired surface) and imprint it with a wax sealing stamp.
Caution: Melting wax requires an open flame and adult supervision is advised. The metal end of the spoon & wax will get HOT when melting the wax.
The shade of the wooden handle may vary.
