Rainbow Windmill Kits (Pack of 6) Self-Assemble, Pre-Cut Card Shapes, 6 Assorted Colours, Approx 13cm Wide

What you're getting

There's something about a spinning windmill that just works, isn't there. These kits come with everything you need to fold and assemble your own—the card shapes are pre-cut, so you're not wrestling with scissors, and you get six of them in assorted colours.

Each one ends up roughly 13cm wide, which is a decent size for actually displaying without it getting lost on a shelf. The folding's straightforward enough that kids can get on with it, and once they're done, they've got something that'll actually spin in the garden rather than just sit there looking at them.
