**9/18/09 Update with more hints**
Great guess, Monica! But that is not what this is. I will give some more hints:
Hint #1 -Mike carries this in his wallet, not because it is useful to him, but because it has sentimental value
Hint # 2 - It is a flexible type of cloth. It has no writing on it.
Hint #3 - Our item is a "left-over piece". The cloth can come in different shapes and sizes. It is the USE of this cloth that makes it significant for our family (and some other families we know). In fact, if someone found this item on the floor, without knowing what it was, he/she would probably just throw it in the trash LOL.
Hint # 4 - I will reveal what this item is, and why it is meaningful to us, tomorrow - 9/19/09 (or sooner if somebody guesses correctly). Yes, that is a hint.
**9/19/09 Update**
Ohhh, good guess, Anonymous! But that is not it.
One last BIG hint, just because I think this is fun...
Hint #5 - While all the members of our family are thankful for this little white cloth, one member of the Party of Ten, in particular, has been holding this item, very dearly in her heart, for exactly two years now :)
