Reusing a Coffee Filter

I did something that was very green and frugal last week without the intention to do so.  On Wednesday we ran out of coffee filters.  The unbleached variety.  It was a busy week and getting the grocery store to purchase more filters was just not in the cards.  So, Wednesday night I put the coffee grounds into my compost pail and then rinsed the coffee filter itself to reuse the next day.  I did this for 4 days before I finally replaced it.  And you know what the filter lasted that whole time!
