TheDroppery.com for trying out new diffuser blends. Not only are there a HUGE variety of blends, but they have the most beautiful and soothing images and captions to go along with them. I feel like the pictures make them smell even better. They appeal to all the senses!
This is the one I have diffusing now and... yes, it IS well in my home!
This website has a page dedicated to blends that use only the Premium Starter Kit oils. Pretty helpful when you're ready to dive in. If you recently got your kit and you're not sure where to turn, turn here! If you WANT to get started with a kit, I can also help with that!
