Hello Anne!!! 17 years ago I started modeling with cold porcelain and I am still learning. If you are starting with modeling, I recommend you look at the tutorials that you find on the internet because they are very helpful and today there are thousands. I did a 3-year modeling course but I also watch a lot of videos and the truth is that they helped me improve a lot, each teacher has a different technique and you learn something from everyone. Greetings. Andrea ❤❤❤
