A sand-art seasonal sweater is decorating Tenby's North Beach this afternoon.

The festive design, to mark Save the Children's Christmas Jumper Day, is the work of Pembrokeshire 'sand circles' artist Marc Treanor.

He had a helping hand from local schoolchildren and volunteers to etch out his artwork.

Marc was approached by the charity to create the jumpers on four Welsh beaches.

He worked on the sands in Anglesey on Friday; Mwnt, near Cardigan yesterday (Sunday) and on Wednesday takes his talent to Barry Island's Whitmore Bay.

Christmas Jumper Day is back for the sixth year running on Friday December 15. Save the Children is expecting over five million people across the UK to take part and help to raise money for vulnerable children around the world.
