Back in the workroom, I inform the designers that Levi's has provided them with notions for the challenge -- zippers, metal buttons, the Levi's insignia, rivets, and a riveting machine. There is no extra shopping trip. And the designers have until midnight of this same day to finish the challenge.

Caroline Calvin is our guest judge. She surprises all of us when she declares that the winning look will be sold as a limited edition on the Levis.com. How thrilling is that?!?!

I just want to add that time management was an egregious issue for the designers. This was the first time this season when I witnessed such a collective meltdown in the workroom. It wasn't pretty. Furthermore, I feared that most of them wouldn't finish.

Finally, there is no immunity for the winner of this challenge, nor will there be for the winner of any future challenges. With so few designers still standing, it's a tougher -- and rougher -- playing field.
