Complete Book of Incense, Oils and Brews by Scott Cunningham
A delightful compendium of recipes for everything from incense to ritual soaps to sachets- the author teases the imagination to come up with ideas even better than what he presents. His chapter on properly substituting ingredients is simply the best of its kind. Cunningham teaches that you need not have wood aloe or dittany of Crete in your magical pantry in order to work magic. Paperback, 269 pages.
