Fit the decorating bag with round tip 16 and fill 1/2 full with medium consistency icing. Hold the decorating bag straight up; the tip should be 1/8 in. above surface as shown. Squeeze bag to form star.
Stop pressure and pull tip straight up and away.
Increase or decrease pressure to change star tip size. Stars will be neatly formed only if you stop squeezing before you pull tip away.
Place stars close enough together so that there are no gaps between. Use this method for star fill-in to cover a section or the entire surface of the cake with stars.
