As with any textile, how long you keep a quilt depends on its fiber content and how you care for it. Proper storage and occasional cleaning will help extend the life of your quilt.
How often you use your quilt also affects its lifespan. If you use it regularly, it will wear out faster than if you only bring it out occasionally. The type of quilt also makes a difference. A pieced quilt made from cotton fabrics will last longer than one made from silk or wool fabrics.
Ideally, you should keep your quilts in a cool, dry place where they won't be exposed to sunlight or intense artificial light. You can store them in an acid-free box or wrapped in unbleached muslin fabric. Be sure to allow them to breathe by not packing them too tightly together.
If your quilts are heirlooms, take extra care to protect them from damage. Have them professionally cleaned every few years and stored in archival-quality materials. With proper care, your quilts can be passed down for generations to come!
