Students at King George V School in Ho Man Tin, have been busy purling and casting on with passion as part of a project to keep Kenyan orphans warm through the winter.
So far, they have knitted over 1,400 woollen squares which are being sewn into blankets to send to an orphanage in the eastern African nation. Blankets have also been sent to one orphanage in Cambodia and another in northern China.
Kirrily Foley, head of religious studies at the school, said the response from students had been 'overwhelming'.
'We have sold over 700 pairs of knitting needles,' she said.
The 'crafts for charity' project was launched last year, but the number of students involved has almost doubled since the beginning of this school year.
Ms Foley said the project had found surprisingly strong support from male students, and was helping to break down gender stereotypes.
'We have more boys involved than in football and rugby combined,' she said.
'It is mostly girls but about a third are boys. They have taken it on as a competitive sport.
'Male and female students of all year groups are knitting all around the school. At lunch time you see students walking down the corridors knitting.'
Twelve-year-old George Chow Kay-wah said there was still some stigma attached to being seen knitting at school but he was undeterred.
'Among my friends, I am the only one involved. They all think knitting is just too girly,' George said. 'But I say it's for a good cause so they should get over it. It is for charity, and can help kids in Kenya stay warm.'
George said he had knitted seven squares since joining the group at the start of term.
'It takes me about a day to knit one square,' he said.
