To achieve a near perfect T-Shirt fold, I use a T-shirt folder.

Place t-shirt face first in line with the T-Shirt Folder.

Fold over right arm of the Folder over.

Pull it back, leaving the T-Shirt sleeve folded.

Repeat with the left sleeve.

Fold up the bottom of the T-Shirt Folder.

And there you have it!! A perfectly folded tshirt.
