I've had several wildly successful soap, lotion and lip balm classes in both Hopkins and Dorr and I asked her if she would like to work with other libraries.  If you are thinking about a bath and body class or just soap, give Rachel Sadowski a call.  She's working in the Hopkins area right now but is willing to travel and often goes to the east side of the state to visit family.  She has a company called Dancing Crane Soap & Sundries on facebook.  She provides all the supplies and instruction.  You have to provide boxes and newspaper to wrap the soap in so that it cools down slowly.
