After all the strands were pulled through, I had to go back and glue every. single. strand. in place. The worst was trying to squeeze where the roof meets the edge of the house. And the nails from the roof. Make sure you are up to date on your tetanus shots...
a much easier alternative is to use glow-in-the-dark stars you affix to the ceiling with poster glue. or just straight glow-in-the-dark paint. you'll get the star effect for awhile, then they'll gently fade as you fall asleep.
