Lay it out on your bed. That might give you a better idea of what you have. I would think that you would be able to find material in shades that would blend with the colors you have in the quilt as of now. Fold it up and take it with you when you go shopping for material..Don't try to do it from memory. The people at your local quilt store may have ideas for you too. Are you going to have this professionally quilted? If so that person may be of help too. Ask other quilting friends,members of your quilting guild or any other quilter you may know. Between all those people and the members of the board you are sure to come up with the perfect solution. Happy quilting!
