Faux Fur Quality Check--Am I Doing It Right?

First of all, thank you to those who gave me advice on how to check the quality of faux fur!

So I went to the Dongdaemun crafts market again today and had a lot of fun (went into the basement and discovered they had shelves upon shelves of large spools of thread, I'm guessing for industrial sewing machines, which was really exciting!), though I'm not sure if I did a good job at it.  Which is why I filmed myself looking at two of the multitudes of faux fur samples that I examined today: http://youtu.be/vmekL0RZOs0

I realize that you probably can't help me determine the quality of the two samples I looked at, but you probably can tell me if I'm checking the quality right (or if I misunderstood the excellent advice and was doing everything all wrong).

And as I'm rather new to working with faux fur (I've worked with other fabrics, though, and even made a dress for my wife with the help of the seamstress mother of a coworker of my father), I'm not entirely sure what the thickness of the backing is supposed to be (and how thin is too thin), or how easy to see the backing is too easy, or if a few strands coming loose when I pet it firmly is bad or admissible.

So thanks for putting up with my questions and I appreciate the help you have been giving me!
