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. Recently, I found a wonderful on-line shop for herbs. Storing them in mason jars makes my heart happy. But labeling them was kind of a pain. So I bought some chalkboard paint.
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.
