Tee hee hee! Most of my Project Linus afghans incorporate cat hair. Don Juan helps me regulate tension by biting the yarn , which means I have to wash them before turning them in.

And... he's also figured out that he can stop me knitting by climbing on my shoulder and parking his 14-pound torso under my chin.

Of course, when the piece gets big enough, he can just lie down on it so I can't turn.
