Just a bit of info about wool and natural fabrics
Most disaster blankets which the OP writes about are made from recycled clothing and fabric, its shredded, and then pressed into whatever form needed.
The slight wool feel to it is caused by the amount of wool fabrics used, which creates a binding effect.
A much safer bet, and a better buy is simple wool fabric. If you can find them at garage sales cheaply are the 100% wool army blankets, the old ones
from WWII, if not those, keep your eyes our for large pieces of wool fabric.
Wool comes in many weights, refinements, and thicknesses. ANY wool fabric is better than a manufactured from scrap or man made material blanket and
here is why- Wool blankets and fabric are just that, fabric that is spun from wool fibers. If left in its original state its warm, and waterproof.
When processed it takes on other properties, it thickens and shrinks some as the fibers pull together, which makes it warmer and even more waterproof.
If it shrinks too much it can be stretched out to its original form while wet, and left to dry in that shape.
Two layers of thin wool fabric over a flannel shirt and pants in the winter time will make you warm enough to sweat because it repels all air. It
will also wick moisture to the outside and away from your skin, while warming you.
I make time period accurate costumes, and on occasion wear them- I can tell you from experience, I have worn a full length long sleeve linen undergown
beneath a full length wool gown on a 100 degree day and been comfortable in the sun or shade, and worn the same clothing on a 9 degree day in the
winter and been comfortably warm and not needed a coat.
Natural fibers are also easier to clean, and soften and mold to your body with wearing. A wool coat that might not fit just right the first couple of
times you wear it will fit better the longer you have it on. Cotton and linen wash clean with water, wool doesn't even have to be washed, it can be
sprinkled lightly with water and hung to dry, or if you have it handy sprayed lightly with grain alcohol and hung to air dry which produces the same
effect as a professional dry cleaning.
Just some bits of fabric trivia
