Overview: Jonnie Irwin is in rural Pembrokeshire house hunting with an ambitious couple who have £650,000 to buy not only their first proper home together, but also accommodation for holidaymakers and a horse. Whilst in the area, Jonnie visits Cardigan and meets a pioneering denim jean producer whose high-calibre clothing has made great strides in recreating local jobs as well as keeping alive the denim manufacturing heritage of this area.
