Family and friends of disabled Lancaster twins Katie and Emma Sutcliffe are pulling together to keep money coming in for the appeal which could help the girls to walk unaided.
The 15-year-olds suffer from spastic diplegic cerebral palsy and need wheelchairs to get around as the condition causes pain and stiffness in their legs.
Backed by the Guardian, Katie and Emma and their family are aiming to raise £85,000 through their Twins Appeal to pay for pioneering treatment in America.
The surgery would mean the girls could walk unaided for the first time.
The appeal has so far raised more than £35,000.
Money raised recently includes £90 from a cake sale held by some office staff on C floor of University House at Lancaster University.
Ashley Ferguson (who organised the recent Where’s Wally night) also organised a sponsored Halloween Fancy Dress pub crawl last weekend.
People visited selected pubs spreading the word about the Twins Appeal and collecting at the same time. The event raised nearly £400.
“I would like to thank everyone who has supported us by donating or organising events, we really do appreciate it,” the twins’ mum Caroline said.
Katie and Emma’s Uncle Luke is doing a tandem skydive at Black Knights Parachute Centre on Sunday, November 4, and will be paying for the cost of the jump himself so that all money raised goes to the appeal.
Meanwhile, his wife Alexandra recently took part in a sponsored horse-ride with her sisters Midge and Wendy for the appeal.
The three hour fell horse ride included walking, trotting and cantering.
“This was a challenge for us as we have joined a riding club with Biglands Hall Equestrian in Back Barrow and after only 12 lessons we are still beginners and have not yet been shown how to canter on the horse,” Alexandra said.
