It’s made of cardboard .....
Despite 3 washes and an overnight soak in a bucket of fabric softener it’s still stiff like I bought it in off the washing line after a good frost, or a teenage boy spent the night having fun with it. 
It’s not a nice stiff like a good decent Egyptian is, but a nasty one. It’s like having a cardboard printed cutout designer handbag instead of the real thing. 
Disappointed, should’ve returned it. But can’t now as I’ve washed it so much and well, it’s standing on my bed. 
Only plus point, don’t have to iron it as it’s too stiff to crease, a bit like a british upper lip
