Hi Everyone, Pete is correct it is called "Yarn Bombing" It is to those you love or have lost this tree has 1500 Crocheted squares on it made from synthetic wool which is not harmful to the tree each square is produced in South Africa by women from poor communities to help boost their income and teach them new skills.
After the yarn squares are taken down these will be washed and made into blankets and sent to Sierra Leone or given to a homeless charity in the local area.
This Tree raised £5,132:75.
Pete Thanks for the Link
Regards John
