GONAAP Faux Fur Throw Blanket Super Soft Cozy Plush Fuzzy Shaggy Blanket for Couch Sofa Bed (Frosty Grey, Throw(50"x60"))

This blanket has flannel backing instead of sherpa (like others that are similar). Is flannel a good backing and why?

Those of you who have successfully washed this blanket. Which detergent did you use. I know heat and the wrong detergent mats polyester fibers.

Pictures in listing show ‘Ice blue’ color as grayish, greenish, and light blue. Which is most accurate?

Why is there such a huge differece in price on different colors? Seems like if you like a certain color you get ripped off.
