The quilt is seeeeewwwww beautiful! I definitely would not try to make any "fixes" now that the quilt is finished. I agree with everyone else, show it!!! You might be very surprised what the judges will overlook and/or not even see. But, defininitely do not try to tea stain the entire quilt at this point. I think tea staining is only for separate fabrics to be used in a quilt and should be done beforehand. (Just mho).
