Or you can even sit it out in a really hot sun..but I iron to be safe..Few ways to go about it but my general method is..Pre-iron the shirt when its nicely stretched on the board..Don't over stretch it. Paint your pic..Take the shirt off the board and turn it inside out..I tend to just place a towel on a flat surface but if you have an ironing board, place it on..I generally place greaseproof paper on the work and another sheet inside the shirt to avoid any color transfer and the like but normally won't happen. Get the iron as hot as it gets (No Steam or water in it at all)..Slowly go over the work for a few minutes as Andre states...After that put the paper aside for use next time, leave the shirt inside out and place in the hottest drying cycle you can in a clothes dryer if you have such handy..If not as I mentioned hang it out in a place where it can get some direct sunlight, warmer the day the better, but if I turn it back inside out so the artwork can get that full suns intensity..Even leave it for a cple days if desired..Then as a final precaution and to test before selling, gently hand wash..Care instructions should also be given to whomever gets the shirt. I always recommend to customers to hand wash rather than machine wash.There are also sealers and the like you can buy to further ensure the integrity of the paint and get a bit more life from the shirt but they tend to be a bit more brand specific and not needed 100%, just that little extra something that can help..Good luck.
