this can be of practical use outside of making regular shirts tall, although that's an added bonus. i've had my fair share of shirts shrink in the wash and i'm a pretty tall guy so i have to stretch some of my shirts so that they'll even fit normally. usually this is a two man job: i fold the shirt in half lengthwise, then get my brother on one end and me on the other. another technique is wedging one side of the shirt in the top part of a door, closing the door, then pulling on the other end.
