Street Medic Wikia (beta), the online resource for street medics that anyone can edit Below are the images we used to make the streetmedic patches used at the G20 in Pittsburgh. These images were circulated among Pittsburgh EMS and through them the entire security apparatus. The first image is what the patch looks like in color. The other two images are the negatives needed to make an effective screen print. Please feel free to alter the patch as you see fit.
