If you do the math, folding a shirt in two seconds means that you are only allowed two folds. You will be making one fold per second, which might sound difficult, but is not.
Put the T-shirt right in front of you. It should be flat and the neck should be facing you. You can either pile up the shirts in this way, or pick one shirt at a time; either way is fine.
Once you have the shirt lying in front of you, simply pick it up by the neck. The front of the shirt will be facing you at this point and both your thumbs will be right at the outer edge of the T-shirt’s neck.
Now press your shirt with the index finger, middle finger and ring finger from the back of the neck until you are holding it perfectly between your three fingers and thumb (both hands). Your little finger should stretch out to the shoulders of the shirt.
In order to give the shirt its first fold, simply join your little fingers in such a way that your wrists move inwards. Both the shoulders of the shirt will be joined after this step.
Now, for the second fold, you simply need to join the top of the shirt with the bottom. This means that the top edge of the shoulders, which have been joined together, should meet the other end of the shirt. You will notice that your shirt has been completely folded after this step. Make sure that you practice both these steps so that everything can be done in a single fluid motion. It will only take you two seconds to complete these folds.
