Join Katie Marquis for a free class on essential oils. She will cover the following questions: What are essential oils? What can they do for you? Is there an oil for that? She will inform us on how to clean our homes, ditch the chemicals, and make our own products. This class is scheduled in the program room at the library. Please call the library to register (860 871-3620) or sign up online at tolland.org/library and scroll down to Online Library Events Calendar.
