The Medford Public Library invites teens in grades 6 to 12 to have henna applied to your hands by a professional artist. These tattoos will remain for approximately one week. This event will take place in the Teen Section and henna will be applied in order of arrival. Space is limited, and sign-up is required through the library’s online calendar. Additionally, participants will need a permission slip signed by a parent or guardian. These permission slips will be available in the Teen Section starting April 1, as well as online. Signed slips can be passed in early or you can bring them with you to the event.
