I use W&N exclusively. it's a little stiff to start, but once the blanket is used and/or washed it drapes much nicer. I don't pre-shrink it. I have a couch snuggler that gets washed a lot because we have dogs that share the sofa with us and so far so good... it's holding up well.
Warm and White is what I used for my design wall boards and I love it!
