This is a lovely duvet set.
I put it on the bed after ironing, as it was creased from packaging. In the eveningI put the light on & a big black Mark was very visible!
It seemed as it was from  when it was packed.
Had to take it all off & wash it! 
However, I must say that the customer service with Wayfair is fab! 
Sorted online with an option to either return free & get a replacement or 20% off.
Black Mark has washed out & I had 20% off for my trouble.
