Is it difficult to learn to decorate birthday cakes?

Difficult to learn! Unless you are highly savvy, it will take more than a year to reach the master level, and experience is accumulated over time. Even if you can do it, you need someone who can keep innovating. I'm a birthday cake maker. I've been working for more than two years, but I can't break through the innovation. This gives me a headache. If I want to learn well, I will go to my relatives' house to practice. If I have no relatives, I will go to a general cake shop to work and learn skills. At first, I will help the decorator clean up.
