If you was wondering What the hell is doing kristen,,, here the answer - But Is she knitting for some scene to Eclipse o to distract herself?

First of all it's EXTREMELY dangerous to knit in a car...Especially one that's driven by Rob :)
The human that can't walk a straight line without falling is knitting...in a car with a vampire...
