I have had Forest Craft on my bookshelf for some time, but I still regularly pull it out to have a flick through. I originally found the book when building up my Forest School resource library along with Forest School Adventure. The look and feel of both of these books, that clearly share an illustration team, was something I was very taken with. Nevertheless, the quality of the books is more than matched by the quality of the contents.
Forest Craft is a fantastic beginners guide to working with wood in an outdoor setting. The first section tells you everything you need to get started even if you have never picked up a knife before. This includes, how to choose woods to carve, all of the basic techniques needed for the projects and even how to keep the blades sharp (a sharp knife is a safe knife).
The crafts themselves start with simple projects such as using Elder to make wands and beads, and then on to more fine projects such as whistles and kazoos. Once you are comfortable with the more basic techniques, you are introduced to more complex and detailed such as carving a skulk of foxes (my personal favourite) or gipsy flowers. Every project is clearly laid out with detailed step-by-step instructions and helpful pictures, making it easy to follow along.

Not only will this book guide you and/or your children through creating great instruments, ornaments and toys but it will also help develop competent knife and tool skills. The benefits of learning to use a knife safely are not just limited to motor control but include building resilience, patience, risk management and self-discipline. All qualities that children need more than ever.
So if you are looking for a beginners book to start to develop knife skills as a family or are interested in teaching others, and/or creating beautiful handcrafts, I heartily recommend this book to get you going.
