There are a few ways that you can align an image on a shirt. You can use transfer paper, which you can find at most craft stores. With transfer paper, you'll need to print your image onto the paper according to the package directions. Once your image is printed, you'll need to cut it out and then peel the paper backing off of the image. Place the image on your shirt where you want it, and then use a heat press or an iron to transfer the image onto the shirt.
Another option is to use heat transfer vinyl. With this method, you'll need to cut your image out of vinyl using a cutting machine. Once your image is cut out, you'll need to weed the vinyl, which just means removing the excess vinyl from around the image. Place the vinyl on your shirt where you want it, and then use a heat press or an iron to transfer the image onto the shirt.
You could also screen print your image onto the shirt. This is a more involved process, and you'll need to have access to screen printing equipment. If you don't have access to screen printing equipment, you can usually find someone who does screen printing who would be willing to print your image onto a shirt for you.
