Lint roll and pre-heat the shirt for 15 seconds. Measuring down 3 inches from the collar, place the design centered on the shirt. Place the black layer down first. I used my Cricut Easy Press 2 at 320 degrees for 15 seconds and it worked wonderfully for both brands of htv. Both brands call for a warm peel of the carrier sheet.
For the mint layer, I had a harder time since I cut through the carrier sheet. I quickly learned to apply letters at an offset while the black vinyl was still warm. This helped hold the mint vinyl in place. Occasionally I had to reheat the shirt before applying more of the mint letters. Again this only happened because I didn’t do a test cut for the Siser vinyl and used the wrong cut settings.
