If folding laundry is a task you put off as long as possible, a t-shirt folder could be just the thing you need. Easy to make and use, you'll be able to fold t-shirts in less than 15 seconds.
Measure and mark the four pieces of your folder. You will need one piece (A) 9 by 12 inches, one piece (B) 9 by 18 inches and two pieces (C) 8 by 30 inches.
Cut your pieces along the marked lines.
Layout your pieces. Place the A piece with its 9-inch long side running horizontally. Place the B piece below A with the same length sides spaced ¼ inch apart. Place each C piece on each side, keeping the ¼ inch spacing.
Run a strip of duct tape or wide masking tape along the three inner sides of A.
Flip the folder over and attach identical strips of duct tape along the same edges, matching the length of the tape. Connect the tape strips in the ¼-inch gaps.
Fold a shirt by laying it face down with the neckline on A. Fold over your C pieces one at a time, and then fold B. Flip over the folded shirt up to show the front.
