BB has compiled a little booklet with photos from past DRF Christmases and a little about the traditions.
You will find the booklet here: Christmas in the DRF
I will write a little to some of the photos.
I will refer to the page and the year, so it should be a simple thing to figure out which it is, and if there are questions, just ask.
Page 04, 1966: Frederik IX and Queen Ingrid celebrated Christmas this year at the hunting lodge in Trend (which they were very fond of BTW) and this was also the first year PH celebrated Christmas in DK.
Page 06, 2010: While M&F (Mary being heavily pregnant) celebrated Christmas at Amalienborg, the Regent Couple went to Schackenborg. IIRC QMII had to be flown by helicopter back to Copenhagen in order to give her New Year speech due to heavy snowfall.
Page 07, 1993: The Christmas tree in the background is decorated in one of the oldest fashions, I.e. in the style in the late 1840's. Modern Christmas trees in DK are much more decorated with much more varied decorations and more colors. This tree however is in a style before the First Schleswigan War, where not even little Dannebrogs were used. The patriotic sentiment during that war led to the extremely widespread use of our flag - and that has never diminished.
Page 08, 2007: It's QMII who decorate the Christmas tree! With a little help from her grandchildren - but firmly under the leadership of farmor Margrethe! Still in one of the oldest traditions.
Page 09: It's also QMII who make the Christmas decorations and indeed decorate the table. If she doesn't make something new, some of the decorations are saved from year to year.
Apart from kravlenisser (see Christmas traditions thread) such decorations are very common in ordinary Danish homes as well.
Page 11, 2003: These are close ups of three tables decorated by QMII and around which they sat at three Christmas Eves. Even the red bouquet in the bottom photo is made from paper by QMII!
Page 12, 1957: Queen Ingrid going Christmas shopping in Copenhagen with her teenage daughter, Margrethe. You will note, no bodyguards, no police officers , not even a LiW.
Page 13: The cup, with the "nisse" (see Christmas traditions) was made for Tzar Alexander and Tzarina Dagmar. Alas, a lackey dropped the set. A new set was ordered and this time the cartoonists behind the "nisser" included a lackey who drops a tray with china...
But also Dagmar's brother, King Georg of Greece got a set and it was so popular that this cup is the only one left of the entire set.
The gift-calendar to the right is a copy of one QMII made for one of her grandchildren. Handmade of course. She made one each for Joachim and Frederik and now she makes eight, one for each of her grandchildren.
Page 14: Each year Benedikte visits the Bering House of Flowers, which is the
Mecca for traditional Christmas tree decorations.
Page 14: The advents wreath (again see Christmas traditions) is originally German (perhaps even Czech) but it was Queen Alexandrine who brought it into the DRF around 1910. She ordered the wreath at a florist in Aarhus, who exhibited the wreath in the window before delivering it (presumably to Marselisborg) and of course now all the ladies of the town ordered one as well.
However the Advents Wreath only became a must in every home in 1940, during the Occupation. When a magazine brought a feature about how the DRF celebrated Christmas. In the traditional form a Danish Advents Wreath is made from green fir, with white candles and hanging in four red ribbons, the national colors. - That has today evolved but is still a must in most homes.
