Warm slippers

My husband is having two major surgeries in the next three weeks. He has lost/misplaced some slippers he had for years so I thought I would try to knit a simple pair up fast. I have been busy taking care of him and everything at the house by myself, and don’t really have time to look thru the patterns here, so I was wondering if any of you great people could either post or direct me to a simple simple (did I say simple?) pattern I could knit up in a hurry to keep his feet warm?

Thanks in advance,
pat.

I thought of doing the felted clogs, but he needs something that can be put on and stay on as the surgery is on his back and I don’t want him slipping around or out of anything.

Bunch of slipper patterns here, and to make them less slippery, check out the felted clog thread under the KAL forum to see what people have used for traction.
