As if finally winning gold at his fourth Olympics wasn't enough, British diver Tom Daley has fueled a huge resurgence in knitting, with his latest creations going for a good cause. The Olympian is using his knitting skills to raise awareness - and much needed funds for the U.K.-based Brain Tumor Charity in memory of his father, Robert, who died of brain cancer in 2011, a year before Daley's Olympic debut at the London Games. He is raffling off sweaters he knitted, which were inspired by the Tokyo games. While many people took to stitching during pandemic lockdowns, Daley said he learned to knit and crochet before the Olympic Games to help him keep calm. He's already been dubbed "the world's biggest crochet influencer.'
