Santa's Factory by Jan van Haasteren - 1000 Piece Jigsaw Puzzle (Jumbo)

There are gnomes on ladders, gnomes on conveyor belts, a gnome asleep in a pile of boxes and one making a very hasty exit with a giant present clutched to his chest. This is Santa's workshop as Jan van Haasteren imagines it: a two-storey factory crammed with reindeer, presents, tinsel and a whole army of little red-hatted helpers who all seem to be doing something different at once.

It's a proper sorting puzzle. Reds, greens and blues repeat everywhere, so you'll be working section by section rather than by colour alone. The staircases, railings and roof beams give you some solid straight lines to anchor onto before you tackle the chaos in the middle.

A poster of the full image is included in the box, which helps no end once you're a few hundred pieces in and need reminding what you're actually looking for.
