Something that I do:
get a bottle of a scented oil that you like -
get yourself a little spray bottle (re-using one of course)
gallon of distilled water
fill the spray bottle with the distilled water, add a drop of two of the oil, shake and there you go...
Shake each time before use (to mix oils, water) ...
We make a boatload of these and even sell them at the local farmers market.
People buy them to spray on themselves and around their houses - they are very versatile....
And with a gallon of water, a bottle of oil - you can many, many refills.
