How to Store Cashmere | Fold Flat, Breathe Free

A favorite cashmere sweater loses its shape and softness fast when stored wrong. Hanging stretches the shoulders permanently. Moisture invites mildew. Moths love soiled fibers. The good news: proper cashmere storage takes about two minutes per garment and protects your investment for years.

Clean and Completely Dry the Garment First

Only store cashmere that is clean and bone-dry. Body oils, food stains, and perspiration attract moths and other pests that will damage the fibers. Wash by hand or use the gentle cycle with cold water and a cashmere-specific detergent — or dry-clean delicate pieces. After washing, lay the sweater flat on a towel to air-dry away from radiators and direct sunlight. Wait until every trace of moisture is gone before folding; storing a damp garment invites mildew and mold that can ruin the fabric permanently.

Fold, Never Hang — Here Is Why

Hanging a cashmere sweater, scarf, or cardigan stretches the shoulders and seams out of shape. The weight of the wet or dry fabric pulls the garment long, leaving ridges at the hanger contact points. The fix is simple: fold the sweater flat, with arms tucked in, and stack it on a shelf, in a drawer, or inside a storage container. For extra protection between stacked layers, place a sheet of acid-free tissue paper between them to help the fibers keep their color and shape.

Choose the Right Container

The container you pick matters as much as how you fold. Breathable materials win every time.

• Best: cotton storage bags, linen totes, garment bags, or open shelving. These let air circulate and prevent condensation.
• Use with caution: plastic bins or vacuum-sealed bags. They are safe only if the cashmere is completely dry and you check the storage every few months — otherwise trapped moisture leads to mildew.
• Avoid: cardboard boxes. They trap heat and moisture, attract pests, and their acids can react with the wool fibers over time.

Location, Light, and Moth Prevention

Even perfectly folded cashmere can yellow, fade, or get eaten if stored in the wrong spot. — away from radiators, heating vents, and direct sunlight. Sunlight fades colors; heat dries and weakens fibers. A closet shelf, under-bed drawer, or dresser works well as long as the area is dry (not a basement prone to dampness).

Moth deterrents are a smart addition, but they need a buffer. Cedar balls, blocks, and lavender sachets repel pests naturally, but their oils can stain cashmere on contact. Place them inside the storage bag or drawer but not directly against the fabric. Replace cedar products at least once a year — the scent fades and so does the protection. Inspect stored items every few months; early detection of a pest problem prevents widespread damage.
