Coffee filters

Whenever I run out of coffee filters, I make my own. It isn't hard. In case you ever want to make your own - or just because you want save a couple of dollars - you can do it like this: take a couple of paper napkins and open them out completely, one on top of the other. Then insert them in the filter holder (receptacle) in your coffeemaker. You can trim the napkins if they are too large.  Put the coffee in. Fold the napkins over the ground coffee. Close the lid and the rest is the same process you normally use to brew coffee. The coffee will taste the same. I know mine does. Of course, this assumes you have not run out of paper napkins. I would not recommend using newspaper paper for this.
