Hi! It's that time of year again! I need help with two questions about lights. I know nothing about electricity except that it can shock and it makes the lights go on. First, I have directions to make a lighted Xmas tree from wire coat hangers. It says to tape the light cord to the hangers. Can you do that? I thought you couldn't put lights on metal? By the way, I'm speaking of the miniature lights. Second, How do people get all those beautiful lights outside without overloading? If I run a weed eater type extension cord and a light stake with two or three outlets in the stake, how many lights can I plug in? I'm really confused about these things. Thanks for your help.
