When you have a large Halloween display, storage and organization become important. You need a way to keep everything from being damaged and keep it organized. Also, as your build gets larger and more complex, you will want to keep related projects together, and plan out the order that you will assemble everything from year to year... so document everything...
Organization:
Organize your items by project or area so you can retrieve all of the items for a given project at once, without having to bring every single box out of storage at once, or having to partially open seven boxes to install one display area. Once I have determined what will fit in a box, I print off a label for the box. I keep a master list of all of the storage boxes and what they contain. The label contains three items:
A large, bold title
A list of items in the box
A number, based on the order I need to retrieve them for installation
The labeled, organized boxes make it easy to go to storage and retrieve boxes 1 through 4 for the first installation, knowing you will have everything you need.
You can see additional photos of our storage at our Christmas Build site.
Document how things are packed!
... you won't remember complicated packs, even if you tink you will!
