Finished graphic designs — pick the design, then the garment, color and size. Original shirts.com artwork plus public-domain museum prints, all printed at full resolution on whatever you choose.
Your words go on as a separate print, so you can drag them under the artwork, pick a typeface and change the colour.
Drag it anywhere, resize it, print the back and sleeves, add more art, clone it, change the garment or add your own words. Everything, on this design.
