I start collecting new items for the outdoor and indoor displays each spring. So, I have items out and around most of the year. There are also items around here and there (like curio cabinets) that were never put away.
Now, so that folks know what I'm talking about here, I have about 30,000+ outdoor lights (running about 150 amps) that I set up each year...alone. So, I try to get to work early on setting them up. I aim for that short period of time when the weather is cool, but not rainy, and most of the leaves have fallen. Playing with electricity and climbing ladders in the rain is not fun, nor is it recommended.
*The official pull out of the outdoor decorations starts in September, cleaning blowmolds, assuring all lights are working, etc.
*I start putting outdoor lights up in mid-October. I start with the lights in the trees and higher reaches, working to the bushes. As it gets closer to Thanksgiving week I start setting out the animated wireframes, and the plastic blowmolds are the last out. This is mostly a weekend project, with the week before Thanksgiving being dedicated (vacation time off work) to setting it all up, plugging it in, and balancing the electrical load.
*The lights go on Thanksgiving night, about the time folks are on their second helping of pie.
Indoor display in picture window seen from outside:
This includes various vintage decorations, motion figures, Dept 56 pieces and the Target Brand Bedford Falls from "It's A Wonderful Life."
*I start pulling things out in July.
*I start setting up in September. I try to have the village completed over the Columbus Day weekend, since I need to start work on the outside.
*These go on Thanksgiving night with the outdoor display.
As for "normal" indoors:
*Lighted garlands and wreaths are up for Thanksgiving Day
The Christmas linens, kitchen/bath items, Christmas trees both live and artificial, etc. All come out the weekend after Thanksgiving.
So you see, I'm not TOTALLY crazy! I remember the days when I put up my outdoor decorations on the Friday and Saturday after Thanksgiving and thought I had a lot of decorations...LOL.
