You would mix the Carrier Oil (base) with the Essential Oil (drops) to the recommended percentage for the intended use.  You may do this by putting a little carrier oil in your hands and adding the recommended drops of the essential oil.  You could also use an empty bottle/jar to mix larger amounts and store them, we offer many glass and plastic empty bottles and jars for this purpose found above in our accessories section of the website.
