Back in March, Christine Kerr (like the rest of us) was puzzling over how she was going to keep busy during lockdown.

"I was in shielding due to an underlying health condition and thought 'well, I've cleaned the house for the fifth time, what else can I do?'

"And then this rainbow idea just popped into my mind. Don't ask me why, because I really have no idea!"

Five months, countless hours and 1.5 miles of knitted rainbow later, and Christine has achieved something truly amazing.

Alongside a central team of three fellow knitters (Julie Eyre, Jean Walker and Trish Williams) and a periphery of occasional contributors, Christine has raised £900 for charity with a piece of knitwear stretching from Windsor Road to Llandough Hospital.

"I thought, right I'll set about getting some wool, which I did. And then everyday I'd write on Facebook requesting donations and volunteers.

"That's when the volunteers started getting involved, particularly through the group Penarth Helping Hands. We had all sorts of ladies, even two 16- and 17-year-old girls. So it went on and on and once it started it couldn't stop.

"So the first rainbow went up on the 27th of April and it culminated yesterday. It's been an amazing five months and now we're all very proud."

The knitting team are loathe to take full credit for the feat. Christine says it was her gratitude for the NHS and the support of the community that guided her needle.

""Llandough nurses were messaging me with their praise and children were counting the rainbows and fascinated as to how it was all going. It felt really good to be so involved in the community!

"We only got two complaints, one of which was just moaning about us getting the order of the rainbow wrong!"

Even more important than brightening up the pavement and passing the time in lockdown is the fundraising element of the project. The £900 donated to Christine's Just Giving page by locals will go to the Cardiff and Vale Health Charity.

In a statement given to Nub News, Simone Joslyn, Head of Cardiff & Vale Arts and Health Charity said: "I'd like to thank Christine and her team of knitters for raising lots of smiles as well as vital funds for our charity.

"The beautiful rainbow-coloured garland has certainly helped to boost morale and put smiles on the faces of the local community and our staff at University Hospital Llandough during a very challenging time."

When something great is achieved - think marathons, works of art, moon landings - those involved often report feelings of deflation, emptiness, and anti-climax. Christine and the team have knitted tirelessly for five months straight. Lockdown hours have been filled. Money has been raised. But what next?

"It's funny, now it's finished I don't know what to do. Four of us were the hardcore knitters, so this morning I woke up and messaged them saying: 'What are we supposed to do now?'"

This reporter, for one, can't wait to see what Christine comes up with next.
