Mix flour, shortening, salt and sugar. Add enough wine to make a stiff workable dough. Roll into ball and let it stand for about 1 hour. Roll out dough 1/8" thick. Cut into 5" squares. Place cannoli tube across the corners of the square. Fold one corner around the tube, then the other and press together. Fry in deep oil, one at a time, until golden brown. Remove cannoli carefully and let cool before filling.
