Hi Donna, Our Christmas Crusader sweater is unfortunately not a knitted sweater but rather a cotton sweater. We do not use iron on decals. We screen print our designs with so the images last a long time. Screen printing is the process of transferring a digital design onto a flat surface using a mesh screen, ink and a squeegee. I can assure you this process is very durable and will last a long time. I show your exchange order was shipped on January 3rd. I will be contacting USPS to see what I can find out in regards to delivery because this should have certainly arrived by now. I will update you as soon as possible. Thank you, Katie Michelle
