I would love to hear more about the final project. There's a group of people in mid-Wales who started a quilting centre a few years ago and the hope is to establish it as a European quilting centre.Music-wise, hymns took over as work-songs among women in Wales... although a great number of hymns of the 19th century used folk tunes (and vice versa), so I can't add anything useful to your search. But I love KickyC's idea...
