Hi, I am new to iron on printing and heat transfers and was wondering how to make an extra large iron on transfer. I would like to make the image bigger than the standard piece of paper that fits in a regular printer. I would like the final printed image to cover a sizeable portion of a t shirt. I see t shirts in stores that are obviously printed on one smooth piece of transfer paper and I have seen them at fairs as well. Any help would be much appreciated, Thank you.
