Street art is woolly thinking
I must reply to all those enthusiastic knitters in Greerton.
It would be so wonderful if the enthusiastic knitters knitted enthusiastically for children who need to be kept warm, rather than trees which don't need it. I've heard of a gentleman who knits to keep children warm.
He gives his jerseys to the public health nurse who distributes them to needy children.
Another point, how do we know that the trees surrounded by knitting don't harbour insects and germs that threaten our vast orchards in the Bay of Plenty?
