The lily nail helps you achieve deeply cupped flowers. You use different size nails for small and large flowers—nails range from 1/2 to 2 1/2 inches in diameter and are available in one-piece and two-piece styles.
To produce flowers in your lily nail, it must first be lined with aluminum foil. This makes removal of the flower from the nail possible! To prevent the foil in your lily nail from moving when piping flowers, squeeze a dab of icing in the nail before adding the foil.
For one-piece nails: Line with a 2-inch square of aluminum foil, pressing foil down smoothly. For two-piece nails: Place a 2 inch square of aluminum foil in the bottom half of the lily nail. Gently press the top half down into the foil, lift off. Some flowers require a shallower foil cup. For those flowers, push foil halfway into the nail.
Hold the lily nail between the thumb and forefinger on your left (right) hand and roll it slowly counterclockwise (clockwise) as you press out icing with the decorating bag held in the right (left) hand. Remove the foil cup with flower and set aside to dry.
