To prepare for the show's commissioning by Cartoon Network, Sugar began assembling a production crew. Jackie Buscarino was engaged as a producer in September 2012 and was tasked with hiring people and supervising the show's crew. During this period of development, Sugar and her team were moved to a building behind the main Cartoon Network studio and based on the same floor as the crew of The Powerpuff Girls CGI special. Some artists who had worked on the special, such as colorist Tiffany Ford and art directors Kevin Dart, Ellie Michalka and Jasmin Lai, were later invited to join the Steven Universe team. Cartoon Network also provided Sugar with a list of suggested writers; when she saw Ben Levin and Matt Burnett (former writers for Level Up) on the list she immediately asked them to join her team because she was familiar with their work. Freelance artist Danny Hynes, whom the former supervising director Ian Jones-Quartey knew from his own project Lakewood Plaza Turbo, became the show's lead character designer. Steven Sugar was assigned as the background designer after his work on the original pilot, and was assisted by Dart, Michalka, Lai, background painter Amanda Winterston and others.
