Gorgeous fabric! You can make a lovely black and white quilt, I've done a red & white one and it's gorgeous, two or three color quilts really make a statement. I would fussy cut a few fabrics and the rest I'd use designs that would showcase the fabrics, like hourglass, friendship stars, I'd stay away from tiny piecing project, unless it's like an Irish Chain that connects a pattern. And several of your fabrics would make fabulous purses and totes! So with the extra fabric, that's what I'd do!
Kind Regards,

PS I'm much like you, I have a 'love affair' with fabric, buy when on sale, and then plan my project.
