Knitting Book on knitting with dog hair

Knitting Book on knitting with dog hair, originally uploaded by CassieWay.

Several years ago, I was commissioned to do a hat and mittens as a gift for this woman's husband. They didn't have kids, and their hairy dog was very special to them. Would I please spin and knit the hat and mittens? Sure, I said. And I did.

Here's a book on that subject!

Knitting Book on knitting with dog hair

This is a book I randomly found on pictures when I was searching for knitting things on google.
Very interesting, knitting with yarn you make out of dog hair/dog fur.
Is it possible?
