First, it is necessary to figure out just how many lights you need. I always average 100 lights per foot of tree – so an 8 foot tree gets 800 lights.
Next, plug in all strands of lights to make sure they are working before you put them on the tree.
Then starting at the top of the tree loosely “wrap” the tree by placing the strands of light just inside the ends of the branches – you don’t want too much of the wires to show, but you do want the lights around the widest parts of the tree. Work your way down the tree, attaching more strands of lights as necessary.
