Instructions
Spread the T-shirt out in front of you on a flat surface. Turn it to where the collar is aiming downward, toward your body. Straighten out the seams evenly.
Grasp the left sleeve and fold inward diagonally. This turns the T-shirt into a triangle-shaped form.
Grasp the right sleeve and fold inward, matching the upper left corner of the fabric. This minimizes the triangle into a smaller one.
Rotate the fabric so that it is shaped like an upside-down right triangle with the point aiming downward, toward your body.
Wrap either end of the triangle inward, meeting the ends. Pull the tip of the triangle upward, matching its end to the overlapped ends in the middle. This creates the diaper form. Pin it into place on the outside with a diaper pin.
