The back serves several crucial functions in a quilt: n It encloses and protects the quilt layers and filling. n It provides structural support and stability to the quilt. n > n It helps prevent the layers from shifting over time. n It allows the quilt to be safely washed and handled without damaging the front design. n In short, a well-made, sturdy back is essential for the long-term care and usability of any quilt. From my experience quilting, I’ve seen quilts with subpar backs lose their shape or have layers shift more quickly over multiple wash/dry cycles.
