Ink converts into a gas during the heat transfer process, and it can bond with adjacent items or layers. Butcher paperact as a barrier to protect your heat plate from unwanted transfer. Infusible Ink Transfer Sheets come with an equal number of protective paper sheets. However, if you plan to cut smaller images from Infusible Ink sheets rather than using full-sheet designs, you will need more butcher paper. It is recommended that each sheet of butcher paper be used one time only, especially if design transfers onto the butcher paper.
