WASHINGTON (AP) — It’s the final stretch of the holiday for President Joe Biden and his wife Jill, who decked out the White House with some whimsical decorations to commemorate the season’s “peace and light.”

The festive display includes a towering Christmas tree surrounded by an amusement park-style carousel, brass-colored bells and sleigh bells lining a hallway, and a ceiling design that mimics snowfall.

The First Lady invited National Guard families to be among the first members of the public to view the decorations, based on the theme “A Time of Peace and Light.” She also spoke at a separate event to thank the volunteers who helped with the monumental work of decorating the interior and exterior of the White House.

“Without your work this wouldn’t be possible,” she said. “It’s been incredible watching you all transform this space year after year, trading time with your families for hours of gluing.”

More than 300 volunteers spent the past week decorating the White House’s public areas and its 83 Christmas trees with nearly 10,000 feet (3,048 meters) of ribbon, more than 28,000 ornaments, over 2,200 paper doves and about 165,000 lights for wreaths, garlands and others to decorate indicates.

The official White House tree, a towering North Carolina Fraser fir anchored to the Blue Room’s ceiling after the removal of a chandelier, stands at the center of a colorful carousel with reindeer, swans and other animals perched on poles rocking up and down. The tree is flooded with twinkling colorful lights and three-dimensional Christmas sweets such as mints and candies. It also bears the names of all U.S. states, territories, and the District of Columbia.

Guests enter the White House under a rotating starlight and quickly come across the Gold Star Tree, which honors the families of fallen service members. The tree consists of six gold-colored stars stacked on top of each other, one for each of the six branches of the military.

The bells in the hallway of the East Colonnade are meant to symbolize the sounds of the holidays. The ceiling and upstairs windows of the East Room are covered in reflective decorations designed to create the illusion of falling snow. Silhouettes of people holding hands decorate the bases of two large Christmas trees that flank the room’s center door.

Light shines through colored glass ornaments and prisms in the Green Room, while paper doves deliver messages of peace in the Red Room. Pigeons also hang over the Cross Hall, which runs between the East Room and the State Dining Room.

In the State Dining Room, a starry sky of sugar shines above the White House’s giant gingerbread house, which includes snow-covered South Grounds with dozens of twinkling mini Christmas trees and a scene of people skating on an ice rink on the South Lawn.

The sugary confection – which is for display purposes only and is never eaten – was made from 25 sheets of gingerbread dough, 10 sheets of sugar cookie dough, 65 pounds (29.48 kilograms) of pastillage, a sugar paste and 45 pounds (20.41 kilograms) of chocolate, 50 pounds (22.68 kilograms) royal icing and 10 pounds (4.54 kilograms) gum paste.

Military families from the USS Delaware and USS Gabrielle Giffords, two Navy ships sponsored by Jill Biden, make paper garlands that decorate the State Dining Room, including two large trees.

As part of Joining Forces, Jill Biden’s White House initiative to support military families, the first lady allowed National Guard families to be the first to experience the decorations. She invited her children — girls in sparkly dresses and shoes and boys in bow ties — to join her on stage as she thanked their parents for serving their country.

The Bidens’ late son, Beau, was a major in the Delaware Army National Guard. He died of brain cancer in 2015 at the age of 46.
