Nearly every verge tree on the street, between Scarborough Beach Road and Ashby Street, has been wrapped in knitting or crocheting.
The anonymous artists who add the decorations to the trees in the middle of the night are known as ‘fairies’ or ‘elves’ to children on the street.
The Mt Hawthorn yarn bombing started in January, but it has occurred at places worldwide since about 2005.
Rhona Smith and her two daughters Ella and Jasmine were excited when they found their tree had been ‘yarn bombed’ about five weeks ago.
‘The girls were squealing with delight,’ Mrs Smith said.
‘It’s a really positive thing. People walk down the street, stop and take photos of the trees.’
