oil diffuser?
I am trying to make my own oil diffuser, but i have fun into a few questions???
do i have to use a bottle or something similar for the diffuser? currently, i have a straight-neck vase..
also, i have liquid potporri? will that work?
thanks!

Making one is not an easy feat, although expensive, it is much better to buy one already made.
Liquid potpourri may smell nice by will not provide the aroma-therapeutic qualities of true therapeutic grade essential oils. For more info check out this link.
