how to put lights on a real christmas tree

The first thing to do is get a real Christmas tree that's tall enough for your room. Then you should have an extension cord ready so you can plug the lights into the wall. Once you've got that set up, you'll need to figure out how many lights you need to cover the whole tree. I would recommend getting a strand of lights with at least 100 bulbs on it. That should be plenty to cover even a large tree.
