I have had a woollen duvet inner that was a double and now I have a single bed I needed a single one. I came on here looking for a single woollen duvet inner and saw alpaca and had no idea what that was like. After a lot of research I bought the alpaca one. I've had it now for a little while and I'm very pleased with it. It's warm, light, well made and sits nicely on my bed. I highly recommend it.
