I've done some of it
I knit about nine of the blocks. I think my colors are too "bold". It will work out better as light weight baby blanket since they are primary colors. If I had to do over I'd use all pastel colors for a scarf. The pattern is very easy to follow without even reading any directions after the first block.
I tried to post a picture but it's too big. I will post it when I get my dh to make it smaller.
