The sublimation transfers are ready to heat press. We use high-quality sublimation printer paper & inks. Sublimation can be done on light-colored fabric containing at least 50% polyester. The higher the polyester count, the better. TRANSFER SIZES Toddler 5.5" - 6.5" Youth 7" - 8" Adult S - XXL 8.5" - 11" These measurements are an estimate & might vary slightly. This measurement will be for the widest part of the image. If you have any questions or want to order a custom size, or design, please send a message. DISCLAIMER Hillside Creations US is not responsible for any pressing errors. Colors may vary slightly from the monitor. RETURNS/EXCHANGES Due to the nature of the product, there will be no returns or exchanges. If there is an issue with your order, please message within 5 days of receiving your order. It is your responsibility to look over the prints before pressing. CHANGES/CUSTOMS I am not able to make changes or edits to any designs. All designs are sold as-is & should remain that way. There should be no editing of the files to change colors, add or remove items, or change the text. Also, I am not able to do custom orders at this time.
