Last 2 years we have made the Christmas tunnel and it is a big hit. People stop by to take pictures and dance under it.
The rows are spaced 6 inches apart and use about 5,000 lights. This year we will add a few extras to spice it up.
We also use 16 channels on LOR.
The arches are made out of 2 ten foot pvc with the green 4 foot post that is used for gardens to support the ends.
Also the pipes were spray painted black to take some of the reflection off.
I did have to hammer the prongs on the side in so the pipe will slide over.
