a n recent years, the (ahem!) humble Christmas jumper has become as much a part of the festive celebrations as turkey, mince pies and repeats on the telly.

Friday, December 15 is Christmas Jumper Day, when the nation dons its finest festive knitwear to work to “make the world better with a sweater’ and raise money for Save The Children.

It’s all for a good cause then, and the shops are full of “tastefully tacky” Christmas sweaters.

Whether it’s a sweater depicting Chewbacca in a Santa hat or Donald Trump as The Grinch, the Christmas sweater is big business.

Not to be a Scrooge, but if you fancy getting crafty this Christmas, why not make your own?

The internet is full of sites where you’ll find easy-to-follow tutorials, and Save the Children have come up with a novel way to make your own Christmas jumper with just office supplies.

Just follow these simple steps, and you can wear this homemade woolly wonder on December 15.

You will need: coloured sticky notes; a cheap, disposable jumper; paper clips; safety pins; tinsel; split pin; sticky stars; empty coffee pod; printer paper.

Steps: Fold some green sticky notes into a tall diamond shape, then attach them to the jumper to mimic a Christmas tree. They should stick to the jumper, but you might need to glue them.

Attach lots of paper clips to each other in a string to create a decoration for the tree.

Layer them in a zigzag pattern and secure to the jumper with safety pins.

Create the baubles by lightly scrunching up some more sticky notes (or you can use sweets).

Attach the baubles to the paper clip string with more safety pins.

Staple some tinsel to the sleeves of the jumper.

Carefully unfold a paper clip, then fold it back on itself to extend the size while not having any pointy bits sticking out.

Place the modified paper clips in a cross shape on the jumper, then place four regular paper clips on top of those diagonally to create a star shape.

Attach the star to the jumper using a split pin, then attach a few stars around the jumper for some extra decoration. Feel free to use small stickers, too.

Peel the foil off a coffee pod and empty the contents. Cut in half to create a half-barrel shape.

Glue the coffee pod to the bottom of the sticky note tree to create the base. Do not do this if you would like to keep the jumper in good condition, as it may be hard to remove.
