Learn how to fold a fitted sheet and win the battle with your linen closet by following these basic steps: Start with your fitted sheet inside-out and held out long with your hands in two corners. Bring your palms together to fold the right corner over the left one. Switch hands and put your right hand into a corner, then use your free left hand to straighten the edges, ending with your left hand in the other corner of the sheet. Bring your palms together again, folding the right corner over the left. After straightening the edges, insert your right hand in the corner and then fold the side down to create a rectangle. Lay the sheet down with the folded edges facing up. Fold the fitted sheet into thirds lengthwise, and then fold into a square.
