well...

Usually you can get a Christmas tree from a Christmas tree... field.
Im not exactly sure what they are called, but a lot of people pick their Christmas trees.

You decorate the tree with ornaments that you can buy at a Christmas store. Some people have special ornaments that are passed down from their family, or are home-made ornaments.

Most people put gifts that are wrapped in special wrapping paper under-neath the tree.

As for stocking... they can be put up for adults, children, and Pets! Ill bet that a lot of people here on Pet Talk hang stockings for their pets!

Well I hope that helps.
