The Art of Preserving Your Woolens
Wool is a living fiber that demands a climate-controlled approach to off-season storage. Treat your knitwear with the same reverence you reserve for your favorite tailoring.
5 min read · IrisThe greatest enemy of a well-made wool sweater isn't the moth—it's the hanger. If you are currently keeping your heavy knitwear on wire or plastic hangers, you are actively stretching the shoulders into permanent, unsightly peaks.
Proper storage is less about complex preservation and more about removing the stressors that cause fiber fatigue. By shifting your perspective from 'hanging' to 'nesting,' you extend the life of your woolens indefinitely.
A sweater should never be forced to carry its own weight for months at a time.
Step one · 2 minutes
The deep clean
Never store wool that has been worn once or twice without a refresh. Even invisible skin oils and food particles act as a dinner bell for pests. Brush your garment with a soft-bristled garment brush to remove surface dust, and ensure it is completely dry before moving to the next stage.
If you detect a faint scent of wear, steam the garment lightly and let it air out for 24 hours.

The folding ritual
Folding is the only acceptable storage method for knitwear. Lay your sweater flat on a clean surface, smoothing out any wrinkles with your palms. Fold the sleeves across the back, then fold the body in half so the hem meets the neckline. Avoid tight creases by placing a layer of acid-free tissue paper between the folds.
Avoid the 'retail fold' if it creates sharp, hard lines; a looser roll is often safer for delicate cashmere.

Select the container
Plastic bins are the death of wool; they trap moisture and create a breeding ground for mildew. Opt for breathable cotton canvas storage bags or cedar chests. If you must use a box, ensure it is made of archival-quality, acid-free cardboard that allows the fibers to breathe.
If using a cedar chest, ensure the wool doesn't touch the raw wood directly to avoid snagging.

Pest prevention
Skip the chemical mothballs, which leave a lingering, toxic stench that is nearly impossible to remove. Instead, use natural cedar blocks or dried lavender sachets. Place these inside your storage container, ensuring they are tucked near the corners rather than directly against the wool.
Refresh cedar blocks by lightly sanding them with fine-grit sandpaper to release the oils.

Location scouting
Store your wool in a cool, dark, and dry environment. Attics and basements are generally poor choices due to temperature fluctuations and humidity. A high shelf in a bedroom closet is the gold standard, as it stays at a consistent room temperature and avoids direct sunlight.
Avoid storing wool near exterior walls, which can harbor condensation.
How to know it works.
Your woolens should emerge from storage feeling supple, not stiff or damp. If you notice a musty scent, the environment is too humid.
Questions at the mirror.
Can I store coats folded?
No. Structure-heavy items like wool overcoats should remain on wide, contoured wooden hangers to maintain the shoulder drape.
What if my sweater is already pilled?
Use a high-quality fabric comb to remove pilling before storage. Storing a pilled garment only makes the knots tighter over time.
