How to Store Yarn: The Complete Guide to Keeping Your Stash in Perfect Shape

1. Moths and Pests

Clothes moths (specifically, their larvae) eat animal fibers — wool, cashmere, alpaca, silk, and angora. They're attracted to dark, undisturbed places, which is exactly where most yarn stashes live. A single moth can lay 50+ eggs, and the larvae can quietly eat through your most expensive yarn before you notice.

At risk: All animal fibers. Safe: Acrylic, cotton, linen, and other plant/synthetic fibers.

2. Moisture and Mildew

Damp conditions breed mold and mildew, which can ruin any fiber type. Basements, garages, and unheated attics are common problem areas. Moisture also attracts silverfish, which eat both natural and synthetic fibers.

3. Sunlight and Heat

UV light fades yarn colors over time — especially natural dyes and lighter colors. Heat can make some yarns (especially acrylic) feel stiff or dry. Direct sunlight in a craft room window can bleach exposed skeins in weeks.

4. Dust and Odors

Open yarn absorbs cooking smells, smoke, pet odors, and household dust. Once yarn absorbs an odor, it's hard to remove without washing — and not all yarn can be washed before it's worked up.

Budget: Ziplock Bags + Bins ($10–30)

The simplest effective system: place skeins in large ziplock bags (squeeze out excess air), then store bags in clear plastic bins with lids. This protects against moths, moisture, dust, and odors.

• Use gallon-size bags for individual skeins or project kits
• Label bags with yarn name, weight, yardage, and fiber content
• Clear bins let you see what's inside without opening
• Stack bins in a closet, under a bed, or on shelves

Mid-Range: Fabric Storage Cubes + Vacuum Bags ($30–80)

Fabric cube organizers look better in a craft room and fit into cube shelving (like Kallax). For long-term storage of yarn you won't use soon, vacuum storage bags compress skeins and create an airtight seal.

• Use one cube per yarn weight or per project
• Add a cedar block or lavender sachet to each cube
• Vacuum bags are excellent for long-term wool storage (moths can't get in)
• Don't vacuum-store yarn you're actively using — it compresses the fibers

Investment: Dedicated Yarn Shelving ($80+)

If your stash is serious, dedicated shelving with baskets or bins is worth the investment. Open shelving makes your yarn collection beautiful and accessible — just make sure the room is climate-controlled.

• Cube shelving (IKEA Kallax or similar) with labeled baskets
• Bookcase-style shelving with clear-front bins
• Repurposed wine rack for displaying cakes and balls
• Pegboard wall with hooks for hanging project bags

Prevention Methods (Safest to Most Aggressive)

1. Sealed containers — Moths can't eat what they can't reach. Ziplock bags, vacuum bags, and sealed bins are your first defense.
2. Cedar blocks or rings — Cedar oil repels moths. Place blocks in storage containers and replace or sand them every 6 months to refresh the scent. Cedar alone isn't enough for a heavy infestation, but it's an excellent preventive.
3. Lavender sachets — Dried lavender repels moths naturally and keeps your yarn smelling fresh. Replace every 3–6 months.
4. Regular inspection — Check stored yarn every few months. Look for small holes, webbing (fine threads between fibers), or tiny larvae (they look like small white worms). Early detection prevents major damage.
5. Freeze treatment — If you suspect moths, seal the affected yarn in a ziplock bag and freeze for 72 hours. This kills eggs, larvae, and adult moths. Thaw, then repeat once more to catch any survivors.

Avoid: Mothballs. They contain chemicals (naphthalene or paradichlorobenzene) that can leave a persistent, unpleasant odor in your yarn and are toxic to pets and children.

By Weight

Group all fingering together, all DK together, all worsted together, etc. This makes it easy to grab yarn when a pattern calls for a specific weight. Label each bin or shelf section clearly.

Best for: Large stashes with many yarn weights. Makes pattern shopping from your stash easy.

By Fiber

Keep all wool together, all cotton together, all acrylic together. This is especially useful for moth prevention — you can add cedar to wool bins and skip it for acrylic.

Best for: People with a mix of natural and synthetic fibers who want targeted pest protection.

By Project

Bundle yarn with its pattern, needles/hooks, and notes in a project bag. One bag = one project, ready to go.

Best for: People who plan projects in advance and want grab-and-go kits.

By Color

The Instagram-worthy option. Organizing by color creates a beautiful visual display, but it's less practical for finding specific weights or fibers. Great for open shelving in a craft room.

Best for: Craft room displays, visual inspiration, and small-to-medium stashes.

Can I store yarn in a garage or attic?

Only if the space is climate-controlled. Unheated garages and attics experience temperature swings and humidity that can damage yarn, attract pests, and cause mildew. If you must use these spaces, use sealed bins with moisture absorbers (silica gel packets) and check regularly.

Should I wind yarn into cakes before storing?

Only if you're going to use it soon. Wound yarn (cakes and balls) is under tension, which can stretch the fibers over time, especially elastic fibers like wool. For long-term storage, keep yarn in its original skein or hank form.

How do I remove a musty smell from yarn?

Place the skeins in a paper bag with an open box of baking soda for 1–2 weeks. The baking soda absorbs odors without leaving residue. For stronger smells, try airing the yarn outdoors on a dry day (out of direct sunlight). As a last resort, gently hand-wash and air dry.

Do I need to wash yarn before using it?

Generally no — new yarn from a store is clean and ready to use. If you've acquired secondhand yarn, yarn from estate sales, or yarn that's been in storage for years, a gentle hand wash can remove dust, odors, and any moth eggs you might not see.

How long can yarn be stored?

Properly stored yarn can last decades. We've seen beautiful projects made from yarn that was stored for 20+ years. The key is sealed containers, climate control, and periodic inspection.
