You’ve heard of Banksy the street artist and you have probably seen Sheppey’s answer to him in the shape of the mini Moo Mop Mouse anonymous paintings along the seafront.

But it looks like the Island has another talented artist brightening up the place in the form of Knitsy.

The secret guerilla knitter has put his or her stamp on Minster, Sheppey, by decorating the bright red village pillar box outside the post office with a striking ‘topper’.

The crocheted artwork appeared out of nowhere sometime on Monday, December 21 and took staff completely by surprise.

Sub-post mistress Nicky Bater said: “The first thing we knew about it was when a customer came in and congratulated us on what we had done to the post box. We had no idea what they were talking about so we went outside to have a look.

“It is stunning and really cheers people up when they see it. It has given us all a smile. But we have no idea who is behind it.”

Until now, the nearest sightings of yarn bombing have been in Herne Bay by the self-styled Cosy Crew. Every year the secret knitters produce damage-free cosies for Christmas. They have even covered an entire telephone box in wool in the past.

Each topper takes about a month to complete and includes ornate seasonal scenes.

The bright red and yellow Minster one features a snowman with a top hat, a pair of Santa’s legs disappearing down a chimney, a Christmas pudding and a robin.

If you know who is behind it, or spot any other examples, email photos and details, in confidence, to timesguardian@thekmgroup.co.uk.
