Cake decoration ideas/tips for a beginner

Hello, This month is my 19th birthday, and I want to make a pink birthday cake in the shape of a heart for myself. I have never decorated a cake this pretty, so any advice or ideas that would be easy for a novice to do would be very appreciated.

I have been browsing Pinterest in search of ideas, but everything there seems really difficult.

In my opinion, this is the simplest cake decorating tip out there. Even if you mess up, it still looks awesome. It’s great for beginners because it’s super easy to use and gives a big confidence boost.
