Cloth Sim: "Help Reproducing a Down Comforter"

Hi, I’m trying to create/simulate a fluffy comforter with seams. I have seen this effect accomplished before, but I haven’t been able to find much information as to how.

I was thinking of pinning the the seams and adding a wind force from below to fluff it up…

Any insight would be greatly appreciate!

(Here is an image of my scene, and one of the effect I’m going for.)
