Hi Jane, thanks for your comments on my blog sorry i didn`t get back to you right away couldn`t figure how to reply so i hope you see this. You are more than welcome to use this in your class and i hope it will be of some help to your students, i am passionate about what i do even though i came into the beauty trade quite late in life i have always enjoyed natural beauty products and over the years have built up quite a lot of information . Hopefully by the time you take your class there will be a lot more information on my blog. Thanks again Joyce.
