Here is how a trunk wrap goes on
We start at the base with the plug end near where power will come from. Then we walk the strand up the trunk in close, even rings, keeping the spacing the same all the way up. At the stopping height we tie it off with a tension wrap so it stays put through wind and rain.
Two colors can go on at once for a striped look, like the red and white wraps in this photo. That takes a bit longer because both strands have to stay parallel, but it is one of the most fun looks on a street full of plain white.
