The award-winning event, the Enchanted Forest, has decorated and lit a condemned elm tree situated next to the Scott Monument in Princes Street.

The tree, which is due to be chopped down early next year, is suffering from Dutch Elm disease, and the team at the Enchanted Forest felt it needed a bit of cheering up.

The elm tree will be sporting a fabulous, cosy jumper that even lights up when it's dark!

The project has involved over 70 volunteers from across Scotland, many of whom are members of the Scottish Women's Rural Institutes, as well as assistance from the Scottish Machine Knitters Association, in preparation for the immense 'tree jumper' that the stricken elm will be sporting.

The wool that has been used has been treated with an ultraviolet dye which, when combined with a specific type of lighting, allows it to glow in the dark — and the effect is stunning.

Marion Davidson, chairman of the SWRI, said: "We were initially 'stumped' when our 'branches' were approached to knit-one-purl-one for the trees of Scotland.

"But we soon twigged that this was the perfect challenge for our nimble-fingered knitters and more than 70 SWRI members from Shetland to the Borders cast on for the campaign."

Mrs Graham from Cupar SWRI said: "This was a great fun project to be involved in and has really brought the branches together to create something unique and wonderful right in the centre of Scotland's capital. I was delighted to be involved."

The elm has already become a cheery site to those visiting the capital, with the Edinburgh Bus Company mentioning it to visitors on its regular city tours.

Tricia Fox, marketing manager for the Enchanted Forest, said: "This project has been several months in planning and we are very grateful to the ladies of the SWRI and SMKA who all gave of their time freely and helped with the knitting — we could not have done it without them.

"The Enchanted Forest is as much about encouraging people to visit the forest as it is a fantastic night out, and we wanted to draw people's attention to how fantastic trees can look, at night when lit up imaginatively."

Tickets for the 2009 Enchanted Forest are on sale now and are selling quickly, with some events already sold out.

The event takes place at Faskally Wood, near Pitlochry, until Sunday, November 1.
