Decide what scent you're going for. This is a great time to scope out your garden (or head to a friend’s house and ask to use some of her flowers) and play with different fragrance combinations.
Place flower petals in a glass jar and cover with vodka. Let sit for 24 hours.
Using a spoon, mash the petals to release the oils, then add the distilled water. Cover and let sit for another 7 days. Every couple days, check on your concoction and use a spoon to mash the petals even further.
Strain the mixture into a glass perfume bottle and store in the fridge when you're not using it.
To use, shake the mixture to blend the oils and spritz on pulse points.
