A couple of years ago my sister, Cindy, re-created an old quilt top she inherited from our Great Grandmother Jennie. The quilt top had some problems so, she took the blocks apart and added sashing and borders to the blocks that were still good. This is the finished and beautiful but smaller quilt.
I am the lucky new owner of an heirloom quilt.
You might be able to do something similar with what you have hiding in a closet.
