Silk duvet cover...drying

[Animals4me]

Possibly this is a weird question but would like to know how to dry a king size duvet cover in the tumble drier without it getting tangled in a tight knot which is then hard to untangle and it therfore isn't dried thoroughly.It is silk one side and cotton the other.I dodn't have accces to a aclthes line and need to be able to wash and dry straightaway.I have been buttoning it and folding into quarters but this has happened twice now so if any one can suggest a way to get it dried without being tangled I would like to know.

Many thanks for any help.

You can't .. You should have dry cleaned it. But dry naturally outside and iron with a bit of steam.
