Anybody ever bought a kids duvet cover from Vertbaudet, I have a weird shaped thing at the bottom

[jenkel]

I have just had delivered a duvet cover and it has a strange shaped thing at the bottom, and no duvet cover fastenings, any idea what I do with it?

Just tuck it in on one side of the duvet and it holds the duvet in (or on my bed it tuck the flap under the mattress and it stays on the bed )

Thanks

Aha! Yup, same with La Redoute. I was mystified, apparently that's right, you tuck the end flap under the end of the mattress.
I can't physically do that here so it annoys the hell out of me. Bl**dy foreigners!!!
