Wool sweaters are one of the easiest pieces to accidentally ruin in the wash — shrinking, stretching, and pilling are all common mistakes. Here's how to actually care for them properly.

Check the Care Label First

Always check the specific care label before washing — wool blends vary, and some can handle a gentle machine cycle while pure wool almost always needs hand washing or a wool-specific cycle.

Hand Washing Wool (The Safest Method)

1. Fill a basin with cool or lukewarm water — never hot, which causes shrinking
2. Add a small amount of wool-specific detergent or a mild, gentle detergent
3. Submerge the sweater and gently press the water through the fabric — never rub, twist, or wring it
4. Let it soak for 10–15 minutes
5. Drain and refill with clean water to rinse, gently pressing out the soap without wringing

Drying Wool Correctly

Never hang a wet wool sweater — the weight of the water will stretch it out of shape. Instead:

• Lay it flat on a clean, dry towel
• Roll the towel up with the sweater inside to press out excess water
• Reshape the sweater to its original dimensions and lay it flat on a fresh dry towel or drying rack to air dry, away from direct sunlight or heat

If You Must Machine Wash

If the care label allows machine washing, use a wool or delicate cycle, cold water, place the sweater inside a mesh laundry bag, and skip the dryer entirely — lay flat to dry as above.

Dealing With Pilling

Light pilling is normal with wear. A fabric shaver or pilling comb, used gently in one direction, removes bobbles without damaging the fibres. Avoid picking pills off by hand, which can pull and thin the fabric.

Storage Tips

Fold wool sweaters rather than hanging them, since hangers can stretch the shoulders out of shape over time. Store in a breathable bag or drawer, not sealed plastic, to prevent moisture buildup.

Final Thoughts

Wool sweaters last for years when washed gently, dried flat, and stored folded — the biggest risks are heat, agitation, and hanging while wet. A little extra care goes a long way with a genuinely good wool piece.
