Four families will compete each week to transform their homes for the holidays.

Christmas DIY details; an elegant animated display; lighting 70-foot trees for charity.

A Mardi Gras Christmas; rooftop carolling; the true meaning of the holiday.

A surprise for the Small family; the Tittiger twins decorate for their parents.

Dancing under the snow machine; driving through a display; a synchronized light show to an original song; getting down to the wire.
