Hello Connecticut!
CarrieC - Thank you so much for taking the time to respond. Having checked the website link, it is not a featherbed that I would like to make (Phew, that keeps the search list down!) but something that is decorative, in a cute fabric, that I have stitched in interesting shapes. I think there must be another name for Eiderdown in the States? I use one at the foot of my bed, over my normal quilt. Kind of like a quilted blanket, but inbetween the quilting that you would do, there is feathers. I am beginning to think it is more niche than I originally believed!
