Gather all your supplies.

Gently heat some water in a saucepan. Make sure the pan is only filled about a quarter of the way, as you don’t want any water getting in the wax.

Meanwhile, layout your bottle caps and place a single wick in each one. You can use a blob of hot glue to fix them in place if you wish.

Now, crush your crayons to make them easier to melt.

Color by color, melt your crayons by tipping them into the old soup can and placing the soup can in the warm water. The heat will gently melt the crayons, preventing them from burning.

If you’re adding essential oils, add a drop once the crayon is fully melted. A drop is all you need, as essential oils are quite strong. If not, just skip this step.

Once your crayons are fully melted, pour the wax into the wicked bottle caps. You can do this over the baking paper to add an extra barrier to any mess.

Let the caps dry until completely solid, then light. Congrats, you’re officially a candlemaker!
