The underside does have a small area showing a very faint colour difference; I think this is from my own storing of the item. I have machine washed it and unfortunately the smudge has not come out.
It is barely noticeable (only in a certain light) and as mentioned it is on the underside and cannot be seen on the upper side. Even if you used this underside as the upper side you may not even notice it.For transparency-sake I had to mention it. Worth mentioning too that it fitted easily into my washing machine, and then tumble dryer.
Easy to iron afterwards also. Did actually think about keeping it! The item "Sanderson Exclusive Bedding Set- Double Duvet Cover Set, Bedspread & Curtains" is in sale since Sunday, February 7, 2021.
