I've got a one size Baby E fitted nappy..Is that the type you are talking about? ...I think mines made out of sherpa.

I don't really use it much..only because it looks a bit old style compared to other fitteds you can buy! It's lovely and though.
Although it's a one size fits most I think for a little bub (newborn or similar) it would be very big..And now although it fits my DD who 14 months, she out wees it straight away and it's a difficult nappy to boost IMO.

Hope that helps a bit! It may suit you guys well though..and especially if they are cheap..wouldn't hurt at all.
