Fit the decorating bag with Multi-Opening Decorating Tip 233 and fill 1/2 full with medium consistency icing. Hold the decorating bag 90° straight up; the tip should be 1/8 in. above surface as shown.
Squeeze bag to form grass. Pull up and away when icing strand is long enough (about 1/2 inch) stop pressure and pull tip away. Grass will be neatly formed only if you stop squeezing before you pull tip away.
For a more natural look sometimes pull tip slightly to the right or left, in stead of straight up. Remember to keep clusters close together so cake does not show through.
