Once upon a time, not all that long ago, there was one thing you could be sure of at a Proenza Schouler show, and that thing was cool. Now, there are two things: cool and craft. Last season, designers Jack McCollough and Lazaro Hernandez obsessed over Japanese shibori dyeing techniques and the process of making guipure lace. For Fall, inspired by a road trip they took to Santa Fe, where they were hipped to the beauty of Native American blankets, they hit the computer to design their own prints. And if that doesn't sound crafty, wait till you hear what happened next. "Then we exploded them and we pixelated them," McCollough said backstage, pointing out the geometric embroideries of a long-sleeved jacquard sheath and the hand-painted panne velvet of other dresses.
