As with all beautiful natural things, your silk, cashmere or wool scarf should be handled with care. When not wearing it, fold it without creasing it, and store it in a dark dry drawer or box. You can also hang it over a padded hanger in your closet. You can iron your scarf at low temperatures, and dry clean only when it becomes soiled.
I like to put herb sachets in the drawer where I keep my scarves; it keeps them fresh and acts as a moth repellant for the wool and cashmere scarves. You can purchase herb sachets, or you can make your own.
Recipe for herb sachets:
2 ounces each of dried rosemary, mint and lavender.
1 ounce of dried thyme
8 ounces of whole cloves
Sew together 3.5 inch square pouches of any tightly woven fabric. Fill with the dried herb mixture, tie the open end with a pretty ribbon, and place in your drawers and closets.
With a minimal amount of care, your purchase will stay beautiful for many, many years.
