I'm thinking the clue is in the name, crafting stuff while in the Bush?, the craft of living off the land. a skill set enabling a comfortable existence living in the wilderness & being at one with nature?
Its all the things that I wish I could do & all the knowledge that I wish I had.
When I'm camping in the woods I'm kit Heavy & to be honist I don't class much of what I do when I'm out and about in the wilds of Scotland as "Bush crafting" I'm in awe of anyone with the manual dexterity to craft using small hand tools crafting things like wooden spoons, kuksas, antler carving, animal skin pouches, trinket boxes, hunting gathering wild food for free, tarp camping & Like Ruud said I also see it as a skill set from which I can draw some knowledge for the different situations I might find myself in when I'm in the wilds.
