Here is an example of using「かき合わせる」.

「寒くなってきたので、私はコートのえりをかき合わせた。」
Because it was getting chilly, I crossed both ends of the collar of my coat so that I could feel any warmer.

So, I guess that sentence means, "Like wearing a cloak, I crossed the ends of the blanket that was hanging on my shoulders across my chest."
