I have been blending herbs for my own herbal teas at night. I used to do this quite frequently when I lived in Tucson and belonged to a co-op with an amazing herb selection, or even being able to go out and gather.

I painted streaks across each jar. This chalkboard paint was in the clearance bin at Michaels for $2.99, but I have recently seen a few recipes for homemade chalkboard paint on Pinterest.
I let it dry overnight, then eh, voila!
