Williamsburg is a loiterer's dream, with endless coffee shops, a gorgeous waterfront and unique boutiques. An absolute must-visit is the Brooklyn Art Library, a haven for creative types right off of the Lorimer stop on the L. The library houses the Sketchbook Project which crowd-sources sketches to create a constantly evolving exhibit. Create a free account before visiting so that you can check out the books and get ready to become lost in the collection. Artists can even submit their own sketchbook.
