12 winding oak trees-13 hours of labor, 3 workers, over 15,000 Multi color LED lights, many staples and an artist for a client who wanted colorful trees to match her soul. This is a very tedious job. The key is to stay consistent and patient. Roll the strand into a tight ball, Find something easy to measure the space between. My wife likes to use her 🖐️ hand. It works for us and it gets the job done. If you can have a partner the job will be much faster, one person in front and back. This is an easy project to accomplish. Disclaimer-DO NOT EVER INSTALL LIGHTS WHILE PLUGGED IN! Also do not puncture the starnd of lights with the staple, you will damage it to a point it may not light up and if water gets on it while installed you can cause a power shortage. Best way to avoid a puncture, buy a battery operated staple gun with control impact settings.
