I started planing this years Christmas show in January; right after I took down last years show. My layout changes every year because I add to the display and move stuff around.
We put out 18 to 20 songs each year. Since I move things around I have to start sequencing early in order to have everything ready by Thanksgiving, which is the target date to turn the show on.
Between sequencing, building controllers, flood lights and this year (new to me) low voltgage strobe lights, I am staying busy. I start in September laying out the display and will work at night (because I do have to work during the day to make a living) and on the weekend right up to Thanksgiving.
I might throw a wrench in my Christmas show this year because I am thinking of putting up a small Halloween show (still thinking about that).
