Zigzag puffs are perfect for borders or for filling in large areas. You can also use this technique to achieve clouds or smoke.
Fit the decorating bag with round tip 16 and fill 1/2 full with medium consistency icing. Hold the bag at a 45° angle at 3:00. Hold the tip lightly touching the surface.
Begin to pipe with a light pressure, then use heavier pressure toward the center of the puff, then return gradually to a light pressure to form the tapered end.
To end each puff, stop pressure and pull away.
Repeat as you move in a straight line to form a row of puffs.
