Dusting off the decorations

Every year, when I get Christmas decorations down from the attic, there's a layer of dust on the boxes.

This year, after having the roof done, the layer was far thicker than usual.

It wasn't too much of a problem though, until one of the boxes slipped and tipped about a ton of this stuff all over my head. Ew. A most unpleasant start to the day.
