This quilt I remember my mother buying this 2-sided quilt from her brother's wife's mother for $25 back in the 1970s. Judging from the woman's age at that time, the quilt was probably made in the 1920s. It was stored in the attic for decades, then in an unused bedroom. However, somehow it got badly stained (I don't know with what, but looks suggestive, like the cats may have gotten to it). I was concerned about how to clean it - I can see places where it's starting to pull apart. Seems a shame to trash it, but in its condition, I am concerned it would disintegrate in the washer. On top of that, the stains may be set in. Best course of action?
