1. Watch short video below.
2. Order supplies.
I strongly suggest you purchase either the Modern Essentials book https://www.aromatools.com/books-media/books-brochures/modern-essentials/current-modern-essentials-edition.html
or The Essential Life book https://www.oillife.com/collections/essential-life
Both of these companies offer many supplies and accessories. I usually buy my roller bottles and spray bottles on Amazon as I've gotten better pricing.
3. Get familiar with doTERRA's products. All blends have trade names and then the type of blend. Here is a reference for you.
4. Once you have supplies, try some of these recipes!
