This is very simple to make, and you can use any essential oil you want! I like Lavender, Lemon, Rosemary, and Peppermint the best. Some great combinations are Lemon Lavender, Vanilla Orange, Lemon Orange, and Peppermint Rosemary. The shelf life of this room spray is about two weeks, so make it in small batches.
