More online about the studio: Betsy Bird visited us in 2011, as the original cast was just settling in, and wrote about the visit for her blog A Fuse #8 Production, here. Robin Rosenthal and Liz Starin visited in 2013 and posted about the visit on their blog Pen & Oink, here. Publishers Weekly reported on a bookseller visit to the studio, organized as part of BookExpo America 2013, in an article here. All of those write-ups were a while ago now, but they seem to have answered everyone's questions.
