I’m buying everyone this carbon negative cardigan for Christmas

I don't know why, but I always like to give my family a nice jumper at Christmas. Maybe because it's one of those things like posh socks, that you never treat yourself to.

This year however, I'll be stepping up my game, because not only have I found the perfect knit, but it's friendly to the planet too. What better idea after the year we've had?

Introducing The Cardigan by Sheep Inc, made from 100% ultra-fine New Zealand Merino wool spun into Italian Cashwool® yarn to make it extra soft.

The unisex design is available in five colours inspired by nature: Tasman blue, clay red, moon grey, moss green and wool white.

Shop now: The Cardigan for £180 from Sheep Inc.

It's the perfect piece to wear on its own or layered over a dress or roll-neck and jeans.

Then you have the environmental and ethical aspect. It's knitted by a second-generation family of knitters in Portugal, with zero-waste, and each sweater comes with a complimentary-coloured NFC provenance tag in the hem and its own New Zealand sheep adoptee.

And 5% of revenue is invested into biodiversity projects to mitigate each sweater’s cradle-to-grave CO2 impact, tenfold, with a minimum of 538 kg of CO2 offset per sweater.

The perfect Christmas present I tell you.

Penny grew up in France and studied languages and law at the Sorbonne Nouvelle University in Paris before moving to the UK for her MA in multimedia journalism at Bournemouth University. She moved to the UK permanently and has never looked back (though she does go back regularly to stock up on cheese and wine).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at MoneySavingExpert.com, sourcing the best deals for everything from restaurants to designer sales.

However she quit after two years to follow her true passion, fashion journalism, and after many years of internships and freelance stints at magazines including Red, Cosmopolitan, Stylist and Good Housekeeping, landed her dream job as the Digital Fashion Editor at Marie Claire UK.

Her favourite part of the job is discovering new brands and meeting designers, and travelling the world to attend events and fashion shows. Seeing her first Chanel runway IRL at Paris Fashion Week was a true pinch-me moment.
