A sugar-based stain will dry clear but turn brown over time. Oils and perspiration from our bodies as well as cosmetics and lotions can oxidize within the fabric over time, damaging the fibers. Once your quilt is clean, there are three factors to consider when it comes to determining the best place to store your quilts. Light or lack of light is very important. Light, especially ultraviolet light, damages the fibers within fabric.
Colors can fade and whites turn yellow.
Controlling the amount of light your stored quilt will be subjected to is essential. This does not mean that you must keep your quilt in the dark forever - simply be aware of the impact of light when storing or displaying your quilt. Storing a quilt in a dark area will protect the fabric, and increase it s longevity. By keeping the quilt in dark storage when not in use, the small amounts of indirect light the quilt receives when you have it out will be relatively harmless. Temperature and humidity together play an important role in the long term care of your quilt.
