I love my Barbie tree. I saw one in a magazine several years and wanted one ever since. The pink trees became popular a couple of years ago - this is a little fiber optic. My two "best" Barbie ornaments (Hallmark) grace the bottom. Most of the ornaments are McDonald's Barbie, and my daughter found a package of small Barbie ornaments the first year I had the tree.
I collect Barbies - not the vintage or terribly expensive ones - but I do have a room full. Chuck loved giving me Barbies, so I have some really pretty ones.
This tree always makes me smile :)
