Join the kids and families from the Neighborhood House Charter School, Saint John Paul II Catholic Academy, the Holmes School and the Henderson School at The Town Field, 200 Park St., Dorchester on Fri., Nov. 24 from 11-3 p.m. as we paint banners to say THANK YOU BOSTON.

Banners that we create with the expert guidance of Dot Art will adorn the construction fences of Martin's Park at the Smith Family Waterfront next to the Boston Children's Museum for the winter months while the Park comes to life.
