I have bought over two dozen quilt tops that were vintage, meaning they were made from 1920-1930 fabrics. I have had to repair almost all of them, put borders on some and do major work. If the seams are extra good and there are really bad stains, I will wash it to get the stains out. I DO NOT recommend washing it to get odors out, hang the top outside, put in a plastic bag with charcoal or vinegar. I hate trimming all the raveling you will get from the seams, it's a huge mess and often the quilt top will just come undone. Because I don't hand quilt, I have had them quilted on a long arm and they are exquisite. My quilter used a pantograph each time to quilt the top. I think I have bought about six butterfly quilts and they have various butterfly pantographs on them. Good luck with your tops.
