I want to do something different...Are there any new exciting techniques I've missed...
What kind of techniques do you normally do on a cake? Maybe if you can tell what you have done then others here on CC will be able to tell you some techniques that you have not tried.
You can start by watching some videos on you tube of which there are thousands to watch on cake decorating. I am a visual person so I learn quicker by watching how to use and hold the piping bags, etc.
Have you ever done crewel embroidery on a cake before? That is a very beautiful technique on a cake. Here is a video below that may help you if you have never tried this before.
