What to do with an old quilt? I got an answer from my great grandmother

I'm still working on reproducing my Great-Grandmother's quilt.  After buying the background fabric at the quilt store, the clerk convinced me to put some of the pieces of the old quilt onto the back of the new quilt.

So I get home and start seperating the quilt top from the batting and backing fabric.  Grandma Bobbi tied the quilt so I simply have to cut the threads.  You will never guess what I found!  Grandma used an old Ohio Star quilt as the batting. 

You can barely make it out because the white background fabric held up, but the colored fabric (looks like it was pink) either deteriorated or was cut out.  It was so cool to find an old quilt tucked into another.

So my Great grandmother has answered my questions about what to do when a quilt is loved to death...sew it into the next quilt and keep passing it on.  Waste nothing.

I feel like she answered my question from heaven.
