According to BBC News:
It took two years for Margaret Seaman, from Great Yarmouth, Norfolk, to make her version of the Sandringham Estate.
The 16ft (5m) by 10ft (3m) creation is now on display in the Ballroom of the Queen’s home in Norfolk [until 14 October.]
The knitted work features Sandringham House, St Mary Magdalene Church, the Nest summer house, the estate’s gardens, miniature woollen visitors and members of the Royal Family.
Mrs Seaman’s work was previously on display at the Norfolk Makers’ Festival in the Forum, Norwich, and raised £8,000 for three Norfolk NHS hospital charity funds.
