Hold the decorating bag at a 45? angle at 3:00 (9:00 for left-handed decorators) with tip slightly above the surface. Squeeze out icing with even pressure, curving tip down and around to the right as if writing a "c". (Left-handed decorators will pipe reverse c's like a comma shape by following the same procedure as above, just curving tip down and around to the left.) Relax pressure at the bottom of the "c" forming a "tail". Stop squeezing and pull tip away.
