HGTV shows you the easy way to fold a fitted sheet. Start with your fitted sheet inside-out, held with your hands in two corners along the long side of the sheet. Bring your palms together and 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.
