After I successfully made my first few batches of soap I discovered so many YouTube videos that made all those fancy color effects look so easy. I prepared myself by watching at least 100 videos before I considered myself an "expert". Of course I hadn't tried it myself yet!
My first dozen attempts all produced some sort of effect, but nothing like what I hoped for. I found out that the most important skills like managing trace and judging soap batter consistency for the effect I needed couldn't be learned by just watching other people doing it. What complicates things is that this is a dynamic process too. You need to judge the consistency for a desired effect into the future - like how it will be a little later when you finally do that hanger swirl or run a chop stick through it all. And so many factors effect all this - soaping temperature, oils used, lye to water percentage, mixing extent, additives, colorants themselves, and on and on! Luckily it's not an exact science, but it really takes a lot of trial and error (I'm really good at the error part! Hahaha!) to gain the experience needed to predict what happens when you mix colors together using various techniques and make it repeatable and consistent. I found keeping detailed notes for each new "experimental" batch helps a lot in this regard.
To me, this learning and experimental part of soap crafting is what makes this all so fun! And the best part is that it never really stops if you don't want it to. No one is going to run out of new things to try.
