First off, it's a beautiful quilt. I just love the fabrics that you have used.
I think I would use the paisley fabric for the drop. I think it would look more neutral than the cream. I know that doesn't sound logical but the paisley, to me anyway, would be more calming and lead the eye to your quilt design.
Let us know what you choose. It seems everyone has many ideas (which is what is so great about quilting). I just think the cream would jump out at you if you know what I mean.
