After you begin to master the curves and swings of the letters, lift the tip up slightly as you write. You'll find you have more control if you let the icing drop to the surface as you write. Practice making a series of "C" curves, trying to make them all the same.
Step 1: Lightly Tough Surface
Holding decorating bag at a 45° angle and using thin consistency icing, squeeze steadily.
Right handers: 45° at 3:00. Left handers: 45° at 9:00
Step 2: Keep Wrist Straight
Glide along surface, wrist straight. Remember to keep your wrist straight, moving your entire forearm as a single unit.
Step 3: Stop Squeezing
Stop squeezing, pull tip away.
