This is what I came up with to try to keep Mom's legs warm. Cold air seeps up the back of her pant leg and her legs freeze! This is felted alpaca on the outside, and lined with polar fleece on the inside. There is a casing at the top and bottom threaded with a length of yarn that I tie shut. Her legs/feet are sometimes swelling a bit, so I wanted it adjustable.
Hey, does anybody know what those little doohickeys are called that are often on sleeping bags or stuff sacks or backpacks, two parts on a spring that you squeeze together to move the doohickey, on a string, and let go when you have it as tight as you want? I think those would work a lot easier than having to tie them, but I don't know what they are called so I can look for them online. Anybody know what they're called or have a link where I can buy a few cheap?
