Storing Handspun Yarn Safely Without Moth Damage

Why Handspun Needs Tailored Storage

Handspun yarn is not like a mass-produced ball of acrylic. It is usually spun in small batches, often from fleece you have chosen, washed and carded yourself, and it carries a value that is measured in hours rather than pounds. That preciousness matters when you come to store it, because the very qualities that make handspun lovely also make it vulnerable.

A loosely spun, airy skein lets air move through it — and moths, damp and dust move through it just as easily. Natural lanolin, spinning oils and the residue of handling at a show or a guild meeting all leave a scent trail that clothes moths find irresistible. Wool, alpaca, cashmere, mohair and silk are all protein fibres, and protein is what moth larvae eat. Cotton and linen will not feed them, but they can still harbour larvae and eggs, so treat every skein as if it needs protecting.

Clean Before You Store

Moths are drawn to soil far more than to wool alone. Anything left unwashed — a skein that has been handled for weeks, one with traces of grease, or a sample that has sat on a windowsill — should be washed first.

• Use a wool-safe detergent and cool water, and never fabric conditioner, which coats the fibres.
• Rinse thoroughly, then press the water out in a clean towel rather than wringing.
• Dry flat in a shaded, airy spot until bone dry. Test the thickest part of the skein against your cheek.

Even a hint of dampness sealed inside a bag will lead to mould long before moths arrive. Keep raw fleece, unwashed fibre and finished yarn in separate places — they have different needs and different risks.

Choose Breathable Containers

The old advice to seal everything in plastic does more harm than good. Wool needs to breathe, and sealed plastic traps any residual moisture against the fibre. Better options are simple and inexpensive:

• Cotton pillowcases or calico drawstring bags, one colour or project per bag.
• Acid-free tissue paper inside a cardboard box with a few ventilation holes punched in the sides.
• Willow or wicker baskets lined with washed cotton cloth.
• Glass jars with rubber seals for your most treasured skeins, opened and aired several times a year.

Split your stash into small, separate parcels rather than one large one. If moths get in, the damage stays contained, and you will spot it sooner. Label each bag with the fibre, weight and date so you can rotate older skeins to the front.

Deterrents, Traps and the Freezer

Cedar blocks, lavender sachets, dried rosemary and cloves all help, but understand what they do: they mask the scent of wool and make a space less appealing. They do not kill eggs or larvae, and they fade. Sand cedar lightly and crush lavender sachets every six to twelve months to release the oils again.

Pheromone traps are the practical partner to deterrents. They catch male moths, so a sudden catch tells you something is happening before you see holes. For a suspected infestation, the freezer is your best tool:

• Seal each skein in an airtight bag and press out as much air as possible.
• Freeze at minus eighteen degrees Celsius for at least seventy-two hours.
• Thaw the sealed bag at room temperature for a full day before opening, so condensation forms on the plastic and not on the wool.
• Repeat the cycle once, roughly a fortnight later, to catch eggs that survived the first freeze.

Where to Keep It

Location does most of the quiet work. Aim for cool, dark, dry and stable — around forty-five to fifty-five per cent relative humidity and below about twenty degrees Celsius. Lofts, garages, cellars and cupboards beside a boiler all swing wildly in temperature and moisture, and that is exactly what moths and mould enjoy. A simple hygrometer costs very little and removes the guesswork.

Keep yarn out of direct sunlight, which fades colour and weakens fibres over time, and away from kitchen and bathroom steam. A wardrobe shelf, a linen press or an interior cupboard in a living room is ideal. Darkness is your friend: moths prefer undisturbed, dim corners, and light keeps your colours truer.

Check Regularly, All Year Round

A stash that is never opened is a stash you cannot protect. Set a reminder to go through everything at each change of season — four times a year is plenty, and it takes less than an hour once you are organised.

• Tip out each skein, shake it gently and air it in the shade for an hour or two.
• Refold or re-coil so creases fall in different places, and check the folds most carefully.
• Look for fine webbing, gritty frass like grains of sand, tiny holes or thin, balding patches.
• Replace or refresh cedar and lavender, and empty pheromone traps.

If you find damage, isolate the affected skein at once, freeze it or let it go, then wipe the area with hot soapy water, vacuum thoroughly and start again with fresh bags. Because a moth's life cycle runs only a couple of months, one thorough check is never enough — it is the rhythm of checking that keeps handspun safe. With clean skeins, breathable bags, a sensible spot and a quarterly look, your yarn will come out of storage as sound and sweet-smelling as the day you wound it.
