For a beginner ultimate frisbee league in Bangor, Maine, one way to attract new players is to be reasonably priced and have cool shirts. In order to keep the price down, we do one color print shirts.
I used fill patterns to create different halftone effects on the shirt. This creates the illusion of the design having different colors/values even though they all are one solid ink print.
The discs are typically printed with a hot-stamp method. This design had too fine of points for this though, so for the disc I made a full color image version which included textures from all over the state of Maine.
