Ruby Tattershall, of Mount Avenue in Great Houghton, came up with the idea and has even paid for the materials out of her own saved-up pocket money.
She is selling the bracelets for a minimum donation of £1.50 and all the money raised is being sent to the emergency fund for Ukraine.
The 11-year-old started the fundraiser last week, with the help of her mum on social media and by spreading the word to friends and family.
“We’re definitely proud of her,” said her mum, Melanie.
“She completely took it on herself and it’s going really well so far.
“She’s sold so many already and it’s still going up.”
Ruby’s dad Ian had told her how Ukrainian miners and their families had sent over donations to the families of British miners on strike back in 1984, when he was eight years old.
He said Ruby had told him how she ‘thinks that favour should be repaid’.
