Folk used to believe that witches could whistle up a wind – maybe one of the reasons whistling women were frowned upon. Sailors used to buy spells from witches to conjure the wind they needed. The spells came as a knotted cord – with each knot untied, the gusts became stronger. If you want to whistle up a wind to dry your washing or simply tinkle your wind chimes, blow in the direction you want go, the wind to visualising it becoming stronger. Ask the spirit to help of the wind you, and always say thanks afterwards.
