I am making a custom Nike Elite Sock buisness with a friend. We bought the heat press, transfer paper, and socks. We put the socks on the press, then placed the design (on transfer paper) on top of the socks, we pressed down on the required temperature, waited 45 seconds. We took the socks out, the transfer paper stuck to the socks but the design did not come off on the socks when we peeled the paper back. WHAT AM I DOING WRONG???? HELP!!!!
