Wrapping lights on a Christmas tree is a bit tricky, but there are a few ways to make it easier. The first way is to start at the top of the tree and work your way down, wrapping the lights around each branch. You can also start in the middle and work your way up and down, wrapping the lights around each branch as you go. Be sure to take your time and make sure the lights are evenly spaced and not too close to each other or the branches might get tangled.
