Everything has some "quality" to it -
The difference being what KIND of "quality" -
poor, fair, good, excellent, etc.
Experience really does seem to be the best teacher for determining what is "good" for a particular use.
And what is appropriate for one use may or may not be appropriate for another.
Extreme example: Cheesecloth is great for straining juices when making jelly. A 1000 thread count sheet would not work well.
