Because it is labeled Ultra "Flannel" Throw Blanket I failed to actually look at the material from which it was made.  Turns out to be 100% polyester. I followed the label and did wash, alone, before using.  It actually bled a lot color (red) which made the water very, very  red. There must have been a lot of red dye used because the polyester blanket is still a deep red,  Actually,  I was hoping it was a flannel blanket however, I am going to keep the polyester version.  Next time I will read the descriptions thoroughly when ever I chose to purchase something else from Wayfair.
