AGE UK Wiltshire is calling on people in the county to take part in a Big Knit campaign.
Knitted woolly hats will be put on Innocent smoothie bottles in retailers nationwide in early 2015 and for each bottle sold, Age UK Wiltshire will receive 25p to help fund winter warmth projects.
Age UK Wiltshire has been tasked with providing 26,500 hats by early October.
Allison Davis of Age UK Wiltshire said: “We want to involve as many local people as possible in this year’s effort.”
Contact Age UK Wiltshire on (01380) 727767 to get a simple hat pattern or to donate wool and needles.
