You might have heard of Margaret Seaman from Norfolk. She's a great great grandmother with a touch of arthritis in her fingers - but that hasn't stopped her knitting the most astonishing models over the last few years.
The 92-year-old's latest creation, a stitched Sandringham, has been given the royal seal of approval and is now on display in the ballroom at Sandringham House.
Among the many visitors already wowed by the model is Her Majesty the Queen, who enjoyed private meeting with Margaret.
The knitted Sandringham has raised thousands of pounds for charity.
Over the years, the fastest fingers in Caister-on-Sea have churned out everything from enchanted woods to Great Yarmouth's Golden Mile.
During the pandemic she even created her very own 'NHS Knittingale'- which she hopes will go to one of Norfolk's hospitals.
She told ITV News Anglia that the Sandringham estate was the hardest thing she had stitched and she nearly gave up but seeing it in the ballroom she said "It's just everything, I couldn't be more proud if I tried, it's wonderful"
You can book tickets to see the masterpiece which will be on show at the Royal estate until October.
