Elephants...started that in high school, but have sort of tapered off lately. For many years I bought one in each country we visited.

Now I try to buy a Christmas ornament from every place we go; it's a nice souvenir that reminds me of our travels every time I decorate the tree.

I also have a fairly large collection of Deparment 56 houses, specifically the Dickens Village. And I've started each of my daughter's on their own collections; one has Christmas in the City and the other one has Santa's Village. We love them!
