This is what I have tried and it works. It?s a teabag for use with loose tea but it works with coffe, too.
But coffe grind swells more than tea so one bag can hold coffee grinds for only 1-2cups. Just have to use more bags for bigger pots.

I?m sure you all get the idea how to use them from the picture. All the text is in finnish and swedish.

PS. At first I didn?t like this bag. It looks a bit like a female hygiene-product. <img src="/images/graemlins/grin.gif" alt="" />
