We would recommend splitting the layers of mesh when heat pressing - you can either thread it onto the lower platen of your press or insert a teflon sheet in between the layers.When applying thermo grip, names and numbers to 100% Nylon mesh football practice jerseys, Is it necessary to open (separate front and back)the jersey? Or can I just put it on the heat press like a regular shirt. I am putting the names and number on the back, the front already have a design on them. I am worried that with the small mesh holes that it will stick together (front and back). Thanks.
