Like any focused design project, 32 Nations will have some ground rules. Why? Two reasons:
First, it makes for better design. The essence of design is problem-solving: working within constraints and around obstactles is what creates worthy work.
Second, Clean Sheet Co. is making and selling these shirts. Each design has to be one that can be beautifully brought to life in the real world – and each one has to feel like a Clean Sheet design.
