And one more idea to add - use it until you are tired of it or ready to take on another project. Then piece a top the same size, and use the birthing method to attach the new pieced top to the flannel side of the quilt. Use a pattern that you can tie down rather than quilt. You will end up with a double sided quilt. Or use the birthing method to attach the quilt to the existing top and quilt down. Either way you recycle the quilt and if in 50 years someone takes it apart, they find a surprise inside! I have done this with other quilts that can't be mended anymore due to hard use.
