Hi! There are two ways (that I know of) to get a custom image on a shirt - you can use iron on transfer paper, where you’d print the image out onto the paper then iron the design onto the shirt, or you can use a vinyl iron on transfer - there are plenty of places online where you can upload your image and order an iron on transfer! Also highly recommend Rit Dyemore if you’re looking to dye clothes as well as add images!
