gerber flatfold gauze cloth diapers

I've used these as burp cloths. They aren't the prettiest things around, but they do the BEST job of any other ones I've tried. They are super absorbent and you comparatively get a lot for your money. I can not give you a review on how great they are at their original intended purpose of diapering, but they are great for lots of other things and have come in handy!
In Summary:
Price: The price of these can really vary. One of the best prices I've found for these is at Buy Buy Baby where they have the pack of 10 for $13.99.
