Review on Utopia Bedding Flat Sheet - Soft Brushed Microfiber - King Size, White – Shrinkage & Fade Resistant – Easy Care by Susan King

I hate real bad reviews but the label says 100% polyester and polyester is notoriously wrinkle resistant and when I received it and took it out of the box it was nothing but hardcore creases that They couldn't see to get rid of so I spent about 4.5 hours with my iron trying to smooth out any wrinkles and then I washed it and hung it to dry and I thought I had smoothed out the wrinkles but then I did put it back in my pocket and now i took it out again to use as a screen for my projector what was the purpose of the purchase and what do i see? Rigid wrinkles that won't go away. It can't be polyester.
