So many valuable nuggets of information are lost every day. (Did you know the first, best, true-red dye came from insects?) There are so many things my grandmother, great-grandmother, and so on knew to do but that have been forgotten by my generation, and this book is one way to claim some of them back again. With this book, if I had to, I could create my own green dye, or blue, or yellow, or red, without having to depend on anyone else to mix a batch of chemicals.
