I agree with red madder. Also once you have it closed as best you can with mostly basting see if replacing a patch or two might look better. Or maybe some kind of thin wonder under type reinforcement behind the repair might help. There are people who repair old quilts ask the closest quilt museum to you for recommend someone. Your grand ma's love for you is what will never change or wear out. Thats way more important than any thing else. Diane C
