Artist: Yellena makes t-shirts

In Yellena's words: "This one is called “Breath” and it is printed on 100% cotton American Apparel Fine Jersey Tees, which are form-fitting and very soft. Thanks to Loric of Evol Twin in Portland for the beautiful screen work! The white designs were printed using discharge inks, which work by removing the dye in the fabric, leaving a much softer texture. So far, I am limited to Medium and Large sizes in Olive Green, Slate Gray, and Galaxy Blue. However, if these do well, I hope to have many more styles and designs to choose from soon!"
