Mix all of your ingredients in a bowl and mix. The vodka helps emulsify the mixture.
Pour the mixture into a spray bottle. I used an empty bottle I had but it was small so I ended up using 2 bottles. A funnel helps so you don't spill it all over.
Just shake well before use and spray. I used lemon oil because its an uplifting scent. If you want a calming scent try lavender. This is safe to use on your linens or just spray in the air.
