Hello. I'm pretty new to FOs so I'm pretty clueless when it comes to the best quality and best smelling oils. I've used fragranceoilfinder as a resource, but it pulls up about a dozen websites. Brambleberry has a green tea and black tea FO. Is anyone familiar with those ones? I was thinking of adding a little Grass Stain FO to the Green Tea to give it more of an authentic "green" smell. Does anyone have any favorites?
