Proof reading other people's work is fun! I've done a few things and even if you don't know the subject you can still deal with the grammar, spelling and punctuation (the last not being my strong point).
If a new bushcraft book were to be written I'd prefer to see one covering new ground - maybe different projects and tutorials rather than a 4th generation re-hash of Lofty Wiseman
That's a good idea. A book that approaches bushcraft from the idea of projects. Chapters on food based around making a spoon, kuksa and hobo stove. Chapter on knife selection, care and usage based on the £5 sharpening set and how to sharpen. So each section is things to make and use. I suppose you're more likely to do bushcraft if you've make the kit yourself. It'll be a load cheaper too. And kind of fits the 'bushcraft ethos' (if there's such a thing).
