These are the various shots doing the "stringwork"... Royal Icing & a tight round nozzle were used to pipe this kind of work. The goal is to pipe in a straight, thin & consistent manner.
Royal Icing dries fast, and breaks easily.
This entire process not only tests one's patience, but also your eye sight. If any lines were broken, you have to start all over and pipe again.
In other parts of the world (western), cake decorators charge them by inch.
So if the cake its done beautifully, it can turn out quite exquisite.
Thanks for viewing.
