Kaleidoscope nourishes the creative spirit. It is a place where all children and their families are invited to be creative, have fun, and feel good about their own special ideas. Provided by Hallmark Cards, Kaleidoscope is FREE! At Kaleidoscope, children use their imaginations to make art with materials from Hallmark’s manufacturing processes. Some are cut into shapes, while others are left just as Hallmark sends them. And Hallmark provides different materials so the projects are ever-changing!
