Design Details: R.BIRD's Patterns

The Patterns series from the design team at R.BIRD are reports full of "professional observations about package design practices within specific product categories." For example, what is the energy of CRUNCH? How do you say CRUNCH with type? What background textures seem to sell CRUNCH? Other reports (each available as a free pdf download) include juices, energy drinks, cold medicines, lo-carb lifestyles... the list goes on.
