11. Week 11: GeekMyTree, Beard Head, Lovepop, PiperWai

A Christmas-decorating aficionado has a high-tech way to deck the halls with animated glow balls and synchronized musical trees; an entrepreneur has whimsical knit hats, complete with detachable facemask; two Harvard grads have a line of ornate, pop-up greeting cards for all occasions; and two women demonstrate their all-natural deodorant made from activated charcoal. Plus, Daymond John gives a workshop to the principals of four of his companies - Bombas Socks, Sunstaches, Myself Belts, and Cozy Bugs - and brings out chef Rocco DiSpirito to provide some delicious inspiration.
