So, I've read some books, been over these forums, watched a million videos on youtube - but I'm not quite sure how everyone learns how to make their own recipes. On this thread http://www.soapmakingforum.com/showthread.php?t=36775&highlight=recipes&page=2 they point out that SoapCalc isn't exact, so how do you know what to adjust? How did you learn what % coconut oil or what % castor oil or how much of a superfat you could use without making a crap bar of soap? Or do you pretty much start with a basic, well known recipe, and do your own tinkering until you like your results? Thanks for the guidance
