That is pretty much how I was taught to wrap bodies some years ago
Blankets come across as another 'I'm a bushcrafter so I must' bla bla bla. If blankets are so good why did people stop using them?
Well, as I asked the question, I will respond, even though I don't see myself as a bushcrafter, or even an aspiring bushcrafter, just someone who goes camping in a style that now a days seems to sit more comfortably in a bushcrafting forum than in a camping forum.
I don't like synthetic material, I have used it extensively when I backpacked (and would again), but find it sweaty, uncomfortable and often have major problems with static.
I don't like being enclosed in sleeping bags, and find it difficult to sleep in them. For years I have been using a sleeping bag unzipped as a quilt, but still find the nylon covering sweaty, clammy and unpleasant. Cotton covered bags, when I've been able to find them are better, but they are also that much bulkier, heavier and get damp more easily than nylon covered bags.
Although, I have a high quality lightweight sleeping quilt, now that I really only camp from the car, or within a short walk of the car, I don't need a high tech sleeping bag and can look at other options.
The first plan was to use a cotton covered domestic quilt, with but you are back to the dampness issue and, even with car camping they can be pretty bulky. Dampness is much less of a problem with wool, and this got me round to thinking of blankets.
I can also see advantages in a blanket as something you can more readily wrap around you when sitting up on cold nights, and something that seems to need less looking after than a sleeping bag.
Asking here seemed a good way of exploring the idea further. My guess is that many people here prefer natural materials and camp close to a car (at least some of the time), or maybe canoe camp, and with some interesting wools available, it may be that blankets are a more realistic option than they were 40-50 years ago, and that maybe nore people than I thought might be using them. It didn't occur to me that it was anything to do with being a "bushcrafter", but equally I'm not sure why that is a problem.
Apart from a few nutters like you and me, people have stopped using primus stoves, but they are an important part of "going camping" for me (not that I use them all the time), and I would have thought they were for you too.
So, I'm not sure why people can't pursue their "bushcrafting" hobby in a way that matches the values they place on what that hobby means to them. If someone wants to use a blanket because that is part of what bushcrafting means to them, why not.
