I made soap 10 years ago I forgot so I started over 2020 to open my own company and buy a book once I had earlier but borrowed and never returned to me.
I had purchased The Natural SoapMaking book for Beginners by KELLY CABLE . Let me tell you it’s awesome and fantastic compare to other writers. Just cost me US$11.93+shipping cost US$7.78 to Taiwan.
