These ready-to-press transfers are physical items that will be mailed to you except for the patch option. Patch prints will be printed on the Patch of my choosing regarding border color and shape unless you contact me directly for further instructions before ordering. It would help if you used a heat press when pressing these transfers. Note: The watermark shown in photos will not be on the printed transfer you receive. Sizing: Mug/Koozie - 3, Infant/Tea Towel - 5 width. Toddler - 8 widths. Youth - 9 width. Adult - 8x10 width. Sizing is approximate and will vary slightly based on the design info: Transfers can be used on any substrate with a polymer coating or polyester. sublimation ink does not bond to natural surfaces or fibers. You can sublimate fabrics made of a polyester blend, but the ink will not adhere to the non-polyester fibers. For the best results, 100% polyester is recommended.
