The Kaufman fabric is interesting. I haven't come across it in the quilt shops yet. Over the years, I routinely find owl, iris, and fdl fabric but key fabric is not that common. I think the pillows could be cute using a subdued blue wavy (to simulate feathers) tone-on-tone fabric.
It comes in a blue colorway as well!
