Soy wax melts are a great way of bringing a lovely burst of essential oil scents to your home. Just light a tealight and place inside your melter, and pop one melt in the bowl on the top. The scent will be released and each melt will smell beautiful for around 8 hours.  So if your tealight lasts 4 hours, you can place another one underneath when the first has finished, and you will keep enjoying the lovely scent!
