Design Size: 12x7
Sublimation transfers work by binding with the polyester fibers in the shirt to leave a soft feel that is not raised.
They must be pressed on a shirt with at least 65% polyester, which will give the image a vintage look. Shirts with 100% polyester will be more bright and vivid.
You must have a heat press to press a sublimation design and they will only work on light color fabrics.
