A mystery craftsperson known as Knitting Banxy who set out to "raise smiles" in town has said she has been humbled by the reaction.
Knitting Banxy, from Syston, Leicestershire, is behind 23 post box toppers which have won a huge social media response and a celebrity fan.
She said she has chosen to keep her identity secret as she "prefers to stay in the shadows".
"It's a bonus I've not been pulled up for suspicious activity," she said.
Her celebrity fans include Line of Duty actor Stephen Graham, who she called "one of the greatest actors of all time".
