It looks so nice! I will give it a try. Can I replace the essential oils with extracts only? Essential oils are expensive where I live (I don't know over there, but here the essencial oils cost between 25 and 12 dollars for a 5 ml bottle, while the extracts cost less than a dollar for a 100 ml bottle. Also, I would like to know how long a jar could last and if I have to store it in the fridge. Thanks!!
