How to hang lights on a christmas tree
Plug the lights in to make sure that each bulb works.
If a few don't, try tightening them-they may not be broken after all. Once you're confident they work, unravel them.

Select from:
(1). You can use a gelatin dropper to remove any stuck-on bits. After disconnecting one bulb from each carbon pod, twist the carbon pod's bottom back end just enough to loosen it from the supporting wires.
(2). This way you don't spend minutes unraveling what you don't use. Spend a couple of minutes tinkering with them, and then if they still don't work, throw them out.
(3). When you have tightened the lights, pull the light tube out of the wall. Repeat this for all the lights on the tree.
(4). Leave a small amount of extra string at the bottom to work with. The last thing you want is for your lights to slide off during light traffic or hot flashes-you never know when your lights might come in handy next.
(2).
