When you decide on a specific heat press material that you want to work with, it is important to keep in mind that many materials will not work when they are layered in two or more color designs. Also, if the material is a cold peel, you will be forced to wait for long periods before heat pressing the second (and sometimes third) color. This is why I recommend the Siser Easyweed for two and more color designs. The Easyweed is pressed at a low temperature (305F) and peeled hot. Even more important, you can heat press the first color for only 2 seconds before peeling and pressing a second color. This speeds up the entire heat press process. Other benefits in heat pressing material this way include less shrinking of the fabric and protecting the fabric from color changing and other damage.
