Citibank parking lot, corner of Myrtle and Clinton Aves, Brooklyn. Crafty little ones learn DIY projects with a different host each week. First, they'll turn old T-shirts into funky jewelry, accessories and home goods with an Etsy star, while younger sibs can play at the Fruiggie organic arts & crafts studio (ages 4 to 7, June 23 at 11am). Musically inclined kiddos should stick around for beatboxing lessons, followed by a little friendly competition (June 23 at 2pm). Try your hand at the art of paper cutting (June 30 at 11am) or finally, dream up cool superheroes and create comic strips (July 7 at 11am). Ages 7 to 10.
