From the Watertown Free Public Library website:

Come learn about braille through exploring braille/print picture books and participating in braille games and activities. A group of young students from Perkins School for the Blind will share their knowledge of braille with library patrons of all ages. Take home a braille alphabet card, have your name produced in braille, use a Perkins brailler, and have fun! Saturday, October 13 from 1:30-3:30 PM in the Children’s Department at the Watertown Free Public Library.
