The last episode of Project Accessory challenged each contestant to design a handbag for a woman featured in eBay’s Style Stories. And there was a lot you didn't see on TV, like mentor Eva Jeanbart-Lorenzotti helping the contestants in the workroom. "To me, I feel like this could snap," she says to Shea Curry of her brown chainstrap purse. "Watch your details, because some of this is really bugging me," she advises Rich Sandomeno on his army-green and copper clutch. When the designers went before judges Molly Sims, InStyle editor Ariel Foxman, and guests Kara Ross and Rebecca Minkoff, Diego Rocha came out on top, while James Sommerfeldt was told to go.
