THE Knitting Nannas set up their display at the Jumpers and Jazz Picnic in the Park yesterday to not only embrace the theme of the festival but also raise awareness about their cause - stopping coal seam gas mining.

The group was established in 2012 by Lismore lady Clare Twomey who has grown the organisation to include 20 groups worldwide.

Mrs Twomey, who sat happily knitting in Leslie Park on Sunday, beside the knitted merchandise said the festival was a great place to make people more aware of the impact of CSG mining.

"Knitting is a peaceful and productive way of making a statement," she said.

"It also passes the time while we watch and observe the miners to collect information, or sit at a blockade to protest, or even just sitting here chatting to people about the cause."

The merchandise, which helps raise funds for the fight against coal seam gas mining, is predominantly black and yellow and ranges from knitted teddies, scarves and beanies to badges, informational DVDs and more.

The group is very resourceful when it comes to fundraising and Mrs Twomey said the money they received from winning one of the Jumpers and Jazz tree categories last year funded a trip to Blackall.

The reason for the journey was to attend the Queensland Rural and Remote Women's Network conference where they erected a life-sized Knitting Nanna to raise awareness.

Mrs Twomey said at the end of the day they hoped to persuade the gas companies to go with alternatives that did not include the destruction of food and water sources.

"Every little bit helps and I am glad we could join in this woolly festival in a different way and hopefully achieve something," she said.
