A wool sweater that spends six months in a plastic bin on a damp basement floor rarely comes out the same garment you put in. The shoulders sag, the cuffs have gone slack, and there are three small holes near the hem that weren't there in March. Most of what we blame on age is really a storage problem, and it's one of the few things in a wardrobe you can fix in an afternoon.

None of it requires special equipment. It requires folding properly, cleaning a sweater before you put it away, and understanding what actually repels moths.

Why Folding Wins, and Why the Pile Matters

Hanging works for jackets and shirts because woven fabric holds its own shape. Knitwear doesn't. A sweater on a hanger keeps stretching in the direction of gravity: shoulders draw into points around the hanger ends, the neckline widens, and the whole garment grows by spring. Fold wool, cashmere, alpaca, and cotton knits, every time.

Folding is only half of it. A drawer stacked eight sweaters deep crushes the ones at the bottom, and ribbing doesn't bounce back from months of compression. Two or three sweaters per stack is the practical ceiling. If a deep drawer tempts you into a taller pile, use dividers to keep the stacks separate and low, and swap which sweaters sit on the bottom from week to week.

How to Fold a Sweater So It Holds Its Shape

Work on a flat surface, not on your lap. A solid fold does most of the work before the sweater ever reaches the drawer.

1. Lay the sweater face down. Button cardigans closed and zip zippers; this keeps the front edges from twisting.
2. Smooth the seams and shake out the sleeves so they lie naturally.
3. Fold each sleeve across the back, angling them slightly downward so the bulk sits below the shoulders rather than across the chest. Cross the second sleeve over the first.
4. Fold the bottom third up toward the shoulders, then fold the whole sweater in half or in thirds, depending on how it fits your drawer.
5. Turn it right side up before it goes in, so the front faces out.

For heavy cable knits and thick lambswool, skip that last fold. Fold the sides in until the sweater is the width of a drawer and lay it flat on its own, or better, on a shelf. Bulky knits carry enough weight of their own.

The file fold

Fold each sweater into a rectangle that can stand upright in the drawer, like a file folder. You can then see every sweater at a glance, pull one out without dismantling the stack, and nothing presses down on the knit below. It takes one extra fold and saves a drawer's worth of rummaging.

Containers: Breathable First, Sealed When It Matters

Wool needs air. It also needs protection from moths, which is where most storage advice gets confusing, because the best container for one problem isn't always best for the other.

• Cotton pillowcases and muslin bags: cheap, breathable, good against dust and light. They won't stop a determined moth, so use them inside a closet you're already managing.
• Acid-free boxes with lids: excellent for fine merino and cashmere, and for anything you want kept flat and undisturbed.
• Cedar chests: the best option if the chest seals reasonably well and you refresh the wood regularly.
• Clear plastic bins: effective against moths if the lid seals and the contents are perfectly clean and dry. Skip them in basements, garages, and humid attics.
• Vacuum bags: fine for a move, not for a season. Compression leaves creases in wool that don't relax, and fibers need to breathe.
• Dry-cleaner plastic: take it off as soon as the sweater comes home. Trapped moisture and solvent fumes do the knit no favors.

Cedar, Lavender, and What Actually Deters Moths

Clothes moth larvae feed on protein fibers: wool, cashmere, mohair, alpaca, silk, and blends containing them. They prefer fabric carrying traces of sweat, skin oils, or food, which is why the sweater you wore all winter and put away unwashed is usually the first to get holes. Wash or dry clean everything before storage, following the care label, and let it dry completely. Bone dry, not almost dry. A hint of dampness invites mildew as well as insects.

Cedar

Cedar's aroma repels moths while the wood is fresh, but the oils fade as it dries. Lightly sand blocks, balls, or chest panels with fine sandpaper every few months, or refresh them with a few drops of cedar oil. Cedar also works best in an enclosed space, inside a drawer, chest, or sealed bin. A cedar hanger in an open closet does almost nothing.

Lavender and other sachets

Lavender, rosemary, and clove sachets smell pleasant and offer mild deterrence. Crush them between your fingers every few weeks to release the oils, and replace them yearly. Treat them as a supporting player, not a solution.

Mothballs and freezing

Mothballs work, but they are strong stuff. Follow the label exactly, keep them away from children and pets, and never open a treated container indoors without ventilation. If you're pregnant, asthmatic, or storing baby clothes, choose another method or ask a professional.

A domestic freezer can kill eggs and larvae in an infested sweater. Seal the garment in a bag, leave it in the freezer for several days, then let it thaw inside the sealed bag so condensation doesn't settle into the fibers before you open it.

A Spring Rotation That Takes an Hour

Storage is a seasonal habit, not a one-time project. When the weather turns, go through your knits in a single pass:

• Sort into keep, mend, and give away. A hole repaired in April is a sweater you still own in October.
• Wash or dry clean everything, then dry it flat and completely.
• Group by weight when you pack: heavy cable knits together, fine merino and cashmere together. Fine knits store better flat in a box than crushed under a fisherman's sweater.
• Label each bag or box with the season and the contents.
• Mid-summer, open every container, check for holes, webbing, or a sandy residue that signals larvae, and air the contents in the shade for a few hours before repacking.

If you spot live moths or clusters of tiny eggs, isolate the affected sweaters at once, freeze or wash them, and clean the drawer or bin with soap and water before anything goes back in.

The Ten-Minute Reset

Once sweaters are stored properly, maintenance is small. Empty one drawer every week or two, refold what's inside, and return only what fits comfortably. Store sweaters clean, keep stacks three deep at most, refresh the cedar, and check your boxes once a season. Do that, and the sweater you loved in November will still fit the way it did then.
