Update: if you are ordering your own plastic figures, we have switched to using OO gauge (1:75) as N gauge (1:150) is just too teeny.

Have you ever wondered what it would be like to explore your house while the height of a five-penny piece? Probably not. It was probably just me who spent too long reading The Borrowers as a child.

But, if you harbour fantasies of being teeny tiny, we'd like to invite you to take part in a pea-sized challenge.

Here's what you do. Send some tiny people on an adventure around your house: swinging off the loo roll, perhaps, or using a mixing bowl as a make-shift diving pool. Turn your home into the epic wilderness it would be if you were only 1cm high.

Take some photos of your people on their adventures and send to me at [email protected] by November 3rd with the subject "Pea-sized challenge." We'll print our favourites in the Great Indoors issue, which will be out in December.

You can obtain a set of five tiny people in our shop, where they come with a set of art cards, or buy a load by searching for OO Gauge people on eBay (just watch out for lengthy international shipping times).
