Save the Children’s ‘make the world better with a sweater’ campaign encourages people from across the country to wear a Christmas jumper on Friday 13th December, in exchange for a £1 donation to help improve the lives of our world’s vulnerable children.

There are many ways to get involved: you can dig out a retro favourite, tinsel up an ordinary sweater or even buy a Christmas jumper. For every Christmas jumper sold at John Lewis, £25 is being donated to Save the Children. However, dear knitters - there is also the option to knit your own full-sized, or miniature jumper to garnish your Christmas tree with (we thought this might be right up your street!) The mini knitted jumper patterns were designed exclusively by the lovely Debbie Bliss, and the full-sized sweater is taken from Sue Stratford’s fabulous new book, Merry Christmas Sweaters, boasting a cheeky snowman. You can get it from our site here!
