Well before i got married i always had a real tree, with multicolored lights and a blue, silver, white and rainbow theme. I had blue, silver and white ornaments. Than i bought a lot of clear ornaments that give kind of a rainbow apperance when the lights shine on them, and i had a icy blue tree skirt with silver glitter.
Now that i'm married we still have the same tree, still a real tree and have all the old ornaments and themes, but now we are making what we call a memory tree, where each year we are going to add some special things to the tree and blend out the old blue, white silver theme over the years. This year we started our memory tree with two special ornaments one from our honeymoon that has the location, the fact that it was out honeymoon and the date on it, and we have a key ornament thats dated and has our first home written on it.
I'll take photos of the tree and post it in a few days.
