Hello there!
We were surprised to find the only Print Areas available on the Gildan 18000 Unisex Sweatshirt from Printful is the front and back. Printful offers other areas like a Sleeve print, which is going to be VITAL for us very shortly when it comes to personalized sweatshirts for Mother's Day that will be here before you know it. Please add Print Areas for each Sleeve on this item from the Printful Integration ASAP. :)
