--A heat press is required...an iron WILL NOT work
--Sublimation transfers can only be pressed onto white or light colored fabrics
--Sublimation does not print white. Any white in the design will be the color of the item you are pressing on to.
--Your item must be at least 50% polyester for the sublimation to work. The end result will be a vintage style design. The higher the polyester in your item, the more vibrant your end result will be.
