That's awesome that your nephew was able to do that for you. It turned out really good too. 👍 seeing the process of how it's all done is interesting. I see that he used a scale to mix the products. It looks like you really have to know what you're doing.
He says using a scale is more precise in case he needs to mix more colour, which he did a few times, and that ensures every batch he mixes is exactly the same shade. #proatwork 🙃
That makes sense to me. It sounds like baking in a way.
