Clean, Naturally
is a pretty comprehensive book on soapmaking by a woman who has her own soap company. It covers everything from the basic from-scratch soap recipes using lye, to glycerin-based melt-and-pour soaps, to home and laundry cleaning recipes.
Each section includes an overview and individual recipes.
Strong points: the wide scope includes in-depth recipes as well as easy recipes that could be made with common ingredients. Good emphasis on healthy herbals and aromatherapy.
Weak points: some recipes are beyond the reach of a beginning hobbyist and would be prohibitively expensive to make, including one with a scent that is only available through the author's company. Could have used more tips and explanations for making your own recipes instead.
