If you don't want to be bothered making anything, there's always a diffuser. I have a few, this is my favorite. Just put some water in the reservoir at the top, add a few drops of fragrance oil, and light a tea light underneath. They work really well. Sometimes, when I have an "empty" bottle of FO, I'll add a little water, shake it up, and then fill the diffuser with that. Not a drop of FO gets wasted! :-DSorry if this is a hijack, but it reminded me that I'm thinking of getting a tart warmer since I could easily make the tarts... any suggestions on an electric one? Do they really work? Do they get icky with dust - I live in a woodsy area with a lot of pollen.
I tried the commercial stick-in-jar-scent-thingie... they just made a mess and didn't put off any scent. I'm still working up to making my own candles but feel foolish buying them when I could whip up a gazillion with the FOs sitting in my closet.
