Whether you're just starting out or you're a seasoned professional, Soapmaking Friend comes with a set of tools to help you develop recipes, guide you through making those recipes, track their progress, manage your inventory and do cost analysis on your batches.
I would suggest to keep it simple. The simpler and the fewer ingredients the quicker you can determine what might be the cause of any problems you have. Once you get a couple of great batches under your belt go ahead and add all the fun options! The things like color, fragrance or natural EO scents, and interesting oils and butters of all sorts.
Best wishes and enjoy your journey!
