Pastry bags and tips enable easy, accurate piping of meringue, whipped cream, or other toppings, fillings, decorative icings, or soft cookie or pastry doughs. The bags are of plastic or plastic-lined cloth; the tips are stainless steel or plastic. Choose larger bags, which are easier to fill and handle. Tips come in a wide variety of shapes and sizes, each designed to achieve a different decorative effect. A plain tip and a star tip will accomplish most simple decorating jobs.
