I was going to bring slippers with me to Idaho, but I forgot. So, I knit a pair of house socks in, like, two days.
I am not ashamed to admit that I use Red Heart. For things like this, it's wonderful. I can throw them in the wash and not have to think twice. Worn over a pair of knitted wool socks, the feet are toasty warm. And in the long run, they are cheaper than slippers.
