Shearing season is upon us but with the price of wool in decline in recent years, the challenge is to find a sustainable use for this natural product. This week, on Country Focus look at Gwnaed a Gwlan - the Made with Wool project, which is finding innovative ways of using Welsh wool and discovering it's potential to revitalise the rural economy. It all starts with the raw product and Caroline Evans first meets with the Williams family at Parlla Isaf Farm in Rhoslefain, in Gwynedd. From there it's on to the Wool Testing Authority in Caernarfon, which is offering farmers the chance to get their wool tested and the potential it has. Finally we discover some of the innovative uses being developed at Bangor University BioComposites Centre. Menter Môn is calling on farmers to get involved!
