Got myself a really cool book, which is rather unusual compared to other works. The systematic approach is centered around plants from the forest.
Centering around plants and their properties and resources, Doris Fischer offers comprehensive botanical knowledge, and describes fun little carving, weaving and dyeing projects, often with really enlightening moments. Learning is fun with this book.
I can really recommend it, especially, but not exclusively if you have kids.
Have fun and take care!
