Lovingisabella, I see some green in the fabric and you said she liked green, if were me, would audtion a light green, not to limey, but a green that is close to that value, you will see a large difference in your fabric as well as not get that harshness that the white is bringing out. The white looks good but makes it crisp, a green would soften it much more, the yellow green I believe someone mentioned, that would be nice. You are right, the black would make to dark and would not see the pattern. If the green is not a go, use a pale blue color that leans more towards the white than the black. That may also be work.
