Cover with Teflon sheet/kraft paper/parchment paper or thin soft cloth
Press for 10-15 seconds with firm pressure (additional pressure may be needed for thick fabricsl)

Vinyl peel Warm (allow transfer and shirt to cool, it should be warm but not hot to the touch, or the transfer will peel right off)
