This artwork was created in Photoshop from a photo of Moth sailboats racing in the Columbia Gorge. I imported this graphic and the provided logos into an Illustrator T-Shirt design template, and arranged the elements to create the final design.
(I was given two shirts with the printed design as a bonus for creating the artwork. The one that actually fits me I often wear on weekends, especially when out on the boat; the Large T-Shirt I wear to the gym and when lazing about on the couch.)
