That is so pretty! I wonder why it was never finished. I agree, don't wash it before it's quilted!

I'm a believer in leaving an antique quilt top just the way it is - unquilted. Hang it over a quilt rack and enjoy it as a top.

It looks to me like some of the brown triangles are pieced with three different pieces of fabric. How cool is that? She used up what she had and made something beautiful. You're lucky to have it whether you finish it or leave it as she left it, unquilted.
