Mainly longjohns and sweatsuits.
I did my usual bathtub washing routine on my buildup of clothes that got to clogging my sinuses and causing the cats to turn up their noses at me when I put them on. I'd been outdoors several times and it honestly didn't feel all that cold.
So I hung everything out on the lines and figured all's gonna be well with the sniffers in a few hours.
A while later I went out to check them and they'd all turned to cardboard on the line.
A couple of hours later I made the uplifting discovery that the cold wind was drying them a bit despite the fact they were frozen stiff as boards.
But now it appears the weather's going sour, so I figured I'd best bring them in and let them dry the rest of the way indoors.
You haven't lived until you pull a pair of longjohns off the clothesline and have them break in half in your hand, except a line of threads holding them together.
