With its walk-in craft project classes ($5-$45), daily and weekly workshops, and sign-up courses, a trip to this Williamsburg shop makes you feel like you're back in summer camp. Children of all ages can stock up on crafting kits and books, then stay to decorate a finger puppet, sculpt a picture frame out of recycled materials, design a barrette or mess around with paint. Special events for little ones include concerts by Rug Bug Music and free storytimes.
