We've got two old duvets we're getting rid of. The filling is of very good quality down, but they are so old that the fabric covering is disintegrating so we've replaced them (it was like a snowstorm when we changed them).
Back home, I would have been able to find someone who wanted to use the filling for craft projects or chicken crates or dog beds or something, but I don't know anyone here.
If anyone is interested, happy to give these to you. We're near Blythe Hill and I'll keep them until our next rubbish pick up on Wens.
