I would stabilize it with Misty Fuse and use a Swiss Batiste for the backing for the Misty Fuse. Then sandwich with batting and backing and quilt. Mistyfuse is a gossamer fusible that virtually disappears when ironed onto fabric and doesn’t change the hand of the cloth. It is permanent, will not wash out.
FYI: A multi national prize winning quilter told me this is how she backs all her quilt tops for entering in shows.
