Start a soaping notebook and keep track of recipes, ingred, fo, color, etc. You may think you will remember everything you did for a certain batch but believe me once you start cranking the soap out, the batches seem to run together and you soon forget. I have a pen handy and write notes as I am soaping on my paper I use to cover my counter space, then transfer those notes into my notebook. I also write on the label of my fo bottle if that certain oil caused acceleration etc - that way I have a record if I had forgotten to take notes or the notes get lost. Happy soapin
