 My handsome guide, Robin telling me about these woolly poles. Cheeky me, I coaxed him to let me take his photo. I told him, we were outside the shop. They call this yarn bombing. May be because I am a grand child of the war. I hate waste.  Knitting takes a long time. To have precious knitting exposed to weathering, fade and tatters and become ugly is not me. In some places, they even wrap tall trees.
In Shenzhen, China , yarn bombing were introduced to wrap trees to keep them warm. It is meant with mixed feeling.
