Wow, at that price I will stick to my down quilt....but I am a Tengu, having feathers is perfectly sensible for me...
But I do have a supply of wool blankets, I just got another the other day, form the charity shop £4.
And I try to look after them, Im finding a use for one which is decidedly past it, and another one I used for work, -made a tunic and wrap which is very effective.
(it can be cold in Iron Age Scotland).
But, interestingly enough, I do possess another piece of bedding.
Its a old sleeping bag of wool batting with a cotton cover. I have removed the zip and use it as a mattress on my folding bed. Its very comfy.
