Sorry for the newbie question but I am heat pressing 60/40 cotton/poly jackets with sequin designs. 450 degrees, 30 seconds using parchment paper cover. It's leaving marks like its burning the garment. I tried pressing pillows but still marks. What am I doing wrong? :/

sounds like too high for to long, lower the heat shorten the time
