Pastry Tubes and Tips Small tubes, referred to as decorating tips, are used for small decorations. Larger tubes, referred to as pastry tubes, are used to pipe large festoons of whipped cream. In the recipes, I have suggested the diameters of the tubes and numbers for the tips where you need to use them. I did not list numbers for the tubes as they vary according to manufacturer. The numbers apply to Wilton, Ateco, and Parrish tips, available at cake decorating supply stores (see Equipment Sources). Be sure to choose seamless stainless steel tubes.
