Under the tree are our M&M village tins. I used to put these along the mantel or on the entertainment center, but I like it so much more having it all together in one location.
We have collected many over the years and have been given a lot by friends and family. And our boys love it.
On the counter next to the tree, I have our M&M advent counter and ceramic M&M house. It is actually a Christmas village piece and lights up.
The train toppers that are not ornaments, I decided to put above one of the cabinets this year. They are out of the way of little hands that have trouble keeping away, but can still be seen.
