I had trouble getting transfers in the center of the shirt, so I came up with a solution. I fold the shirt in half the press long enough to creat a crease in the middle of the shirt. Use something that is half the distance of you press and use this to line up the crease in the middle of the press. I use a set of calipers since I was a machinest, but a ruler will work fine. This take the guess work out of getting the transfer in the center of your shirt and it doesn't cost anything.
