What can I use in place of a coffee filter, as I have run out and am stuck in the middle of a blizzard?
If have a roll of paper towel or napkins lying around, just shape them to fit inside your coffee maker and you can start brewing your coffee. You can also substitute the coffee filter with a cheese cloth or butter muslin.
Use a Scott towel. They work just fine. I always use them in a pinch.
Paper-towels, bed-sheet, pantyhose, handkerchief...
