Sienna screen prints these shirts in the studio in St Johns. This shirt uses an aqua blue ink on heather navy Bella Canvas tee shirt. Sizing listed below.

Care: Wash in cool water. Optional: turn the clothing inside out to further protect the image. (This is the best way to care for a screen printed piece of clothing, but these tend to hold up pretty well in the wash otherwise. They just won’t last as long if not properly cared for).
