Mary, I went to the show last year for the 1st time. It was a nice show, adequate but not as large as the AQS shows or the Mancuso shows. There are usually great teachers, but I didn't take any classes. Just down the street from where the show is held, is the New England Quilt Museum and the American Textile Museum. Put all 3 together and you'd have a great time for the day.
What are you hoping to see in Boston ?
