I am watching videos which show how to make embeds. It was stated that the embeds must be the same type of base as the other soap they are going in. So using a MP soap to make embeds or buying pre-made ones won't work with making a HP/ CP soap right? So if I want to make embeds I imagine I need a small batch...of the same soap for the bars. Do I just use a calculator and break the recipe down and make a little bit? or can I use the MP? Or maybe only use embeds with MP? I am guessing it is tricky to get the timing right otherwise?
