This cake had pale yellow icing with white lace piped onto the tiers.
The pearls were made from fondant and dusted with a pearl dust.
I piped this on freehand, using a piece of lace as a guide for the pattern. When you pipe lace it's usually a good idea to mark off some main guidelines for yourself to follow to keep the scale of each piece equal to the others. Also, only put a small amount of icing in the piping bag so that the heat from your hands doesn't soften the icing since you want the lines to be crisp.
