Bath Teas

I'm working on a new line of bath products called "Bath Teas." They are comprised of dried herbs and spices along with dried tea leaves. I saw a vendor at a recent festival I visited selling something similar and it inspired me. The idea is to pour a few spoonfuls under hot bath water and let it turn your tub into a soothing, fragrant place where you can steep yourself.
I think it's fairly unique- not a soap or a salt, but will be equally healthful for skin and pleasing to the senses.
I'm making a few small batches so that I can debut the teas at the crafts fair I'm organizing in mid-October, we're still not 100% sure about the date yet, we have it narrowed down to two days. I'm working on advertising and finding vendors.
Tomorrow I have to go into town to the home and garden shop to buy some more terracotta pots for my indoor winter herb garden.
