Using a decorating bag fitted with either Tip 104 or 127, hold the bag with the wide end of the tip touching the surface of the Flower Nail, keeping the narrow end slightly above the surface. This is your starting position.
Squeeze as you turn the Flower Nail (a small turn will create a narrow petal, a large turn will create a wide petal). While keeping steady pressure, move the tip slightly upward then back down, forming a petal shape.
Relax pressure as you come to the base of the petal. Turn the Flower Nail to pipe subsequent petals. Pipe a center if desired using Tip 2.
