Finding a hole in your jersey or worse yet – in one of your favourite thick socks – is bad news at this time of year.
If you mend your own clothing (rather than replacing it) you'll not only be helping out the planet, you'll also value it more, says Bernadette Casey from Wellington textile company The Formary.

Bernadette defines 'darning' as 'repairing clothes that you love' by reconnecting threads that have broken – "joining the garment back together, really".
She's running a workshop called The Art of Darning at Wellington's Nairn Street Cottage this weekend.
Bernadette says there's been a lot of interest in it because people are now more aware than ever of the stress excessive clothing manufacture is putting on the environment.
"It has a really significant impact on our carbon production, as a planet."
