I agree with Tartan. Either find a cream color solid to match or find something that will look like it belongs. Maybe a dragonfly?? You can then place a few more scattered on the quilt. You are so lucky you found this beautiful quilt. I have a book that goes thru restoration step by step. The name is Quilt Restoration A Practical Guide by Camile Dalphond Cognac. See if your local library can borrow this book from another institution.
