Be very careful with an old quilt. I found a quilt top made by my grandmother made in about 1920 for my mother but never finished. I found the top in a brown paper bag some forty years after my mother died, in 1984 and it was stained. I did everything wrong and tried all I could think of to get the blood stains out. WRONG MOVE I know now. Never wash or use any chemical but ORVIS a neutral soap to wash the quilt, and be careful. You can buy QRVIS at anyplace that sells farm foods for animals for it is used to wash horses and farm animals. This is what an archivist told me too late. Don't use WOOL LITE she said. But I'd done the damage and over the years parts of the quilt have continued to fade in the vegetable dyes blocks. This was a feathered star, hand sewn with a green star center of vegetable dye. I was not into quilting but had the quilt finished and hand quilted in Ozark, Missouri and love it anyway> Justme CA
