I did a third set of bath salts with juniper and a hint of peppermint. The dash of peppermint seems to work really well with the pine-juniper-wood types of scents, to add a brightness to it. I enjoyed that a lot.
I think my favorite is still the lavender-ginger. Although I just got in some lemon and tangerine oil, so I'll try those soon. Citrus scents are nice.
What are your favorites?
