Take a big spoon and mix it all together.
Now this is the part that I do differently than most...I don't like "chunky" powder...I wanted mine to look more like store bought and I also wanted to scent it. So I took 5 cups at a time and put it in my blender..I also added 15 drops of the essential oil. Then I blended it til it was smooth. I forgot to take a pic of the oil...I got it a health food store and it was lavender/vanilla.
