Gearing up for its second annual Hudson River Pageant on May 22, Earth Celebrations is holding free puppet and costume workshops for teens and adults to create the pageant’s spectacular costumes, masks and giant puppets, all inspired by the Hudson’s diverse marine species. The workshops are at the World Financial Center, 220 Vesey St., courtyard gallery (second level, above the food court, near the Winter Garden, just off the Hudson River), Wednesdays, 6 p.m. to 9 p.m., for costumes, and Saturdays, noon to 4 p.m., for puppets.
