I just had a quick thought of inspiration. I'm not sure how big you are on aromatherapy If i were you, I would add a drop of lavender oil to the masks for that "extra" touch. Lavender is associated with calming. I have a first hand experience with the power of lavender when I had a crazy mare that was not willing to simmer down so that I could take a look at a wound of her's. I went in and got some lavender oil and rubbed it on my hands. I took a big whiff, she took a big whiff and we both calmed down long enough to get her fixed up and back out. Needless to say I didn't keep the horse much longer as she was certifiably crazy, but the lavender definately works
just a quick suggestion! Obviously the oil will come out in the wash but it will have the same effect like "new car smell" ha!
