Fabric Care

Merino wool is naturally soft, breathable, and long-lasting — and with just a little care, it can stay that way for years. Here’s how to keep your Mason William pieces in top condition.

1.Washing Your Wool

CARE INSTRUCTIONS
• Machine wash on gentle cycle (max 30°C)
• Use a wool-specific detergent
• Place in a laundry bag (recommended to avoid damage from zippers or rough garments)
• Do not bleach or tumble dry
• Do not wring, twist, or rub
• Dry flat in the shade
• Do not use fabric softeners
• Do not apply detergent directly onto the garment

2.Drying

• Dry flat in the shade
After washing, reshape your garment and lay it flat to dry. Avoid direct sunlight or tumble dryers — both can cause shrinkage or fading.
• Don’t hang heavy wet items
Wet wool can stretch out of shape if hung. Always dry flat to preserve the garment’s structure.

3.Ironing Your Wool

Merino wool has a natural elasticity, so most of the time it doesn’t need ironing at all. After washing, simply lay your garment flat to dry — it will often bounce back into shape on its own. Always refer to the care label for ironing instructions.

Tips for Easy Ironing
• Use the ‘Wool’ Setting
Select a low heat setting with steam. If your iron doesn’t have a wool option, use a cool temperature and a pressing cloth to protect the fabric.
• Steam Is Your Best Friend
Light steam relaxes the fibres and smooths out wrinkles. A quick pass is usually all it takes.
• Avoid Ribbed Hems and Cuffs
These parts are meant to stretch and recover naturally — ironing them can flatten their structure.

4.Storing Your Wool Garments

Merino wool is a natural protein fibre — soft, breathable, and biodegradable. But like all natural fibres, it needs proper care when not in use.

How to Store Your Mason William Pieces
• Always store clean
Moths and silverfish are drawn to microscopic stains, including sweat or skin oils. Always wash your garments before storing for the season.
• Use a sealed bag or box
Store in a breathable, sealed garment bag or plastic container to keep pests out and your wool fresh. Avoid leaving garments lying around in laundry baskets or on chairs for long periods.
• Freeze before storing (optional but effective)
To help kill any potential larvae or eggs, pop your garments in a sealed bag and freeze them overnight before long-term storage.
• Add natural deterrents
Herbal sachets, a bar of soap, cedar balls, or clothing mists can help keep insects at bay — moths dislike strong smells. Be sure not to apply mists directly onto the garment — instead, mist the wardrobe or place sachets nearby.
• Avoid hanging heavy knits
Fold jumpers and heavier items to prevent stretching. Lighter pieces like scarves or tees can be hung if preferred.

5.Help! Small holes have appeared in my clothing.

Don’t worry — this is a common issue with natural fibres and doesn’t mean your garment is faulty.

The most likely causes:
• Biological detergents that contain bleach or enzymes can weaken merino fibres, leading to holes after washing.
• Moths and silverfish are the most common culprits. Their larvae feed on high-protein fibres like merino wool, creating tiny holes that often show up after wearing or washing.
• These insects can target just one item, even if stored with others, and may come from travel, hotel stays, or seasonal storage — not necessarily from your home.

To prevent this:
• Always wash garments before storing.
• Use sealed storage bags or boxes.
• Consider freezing items before long-term storage to kill any hidden larvae. (optional)

6.Repairs & Mending

General wear and tear is a natural part of a well-loved garment — small holes, fraying edges, seam wear or even the occasional stain don’t mean it’s time to say goodbye.

One of the best solutions for minor damage is invisible mending — a fine, discreet stitching technique that closes small holes (like those caused by moths or snags) and strengthens the surrounding fibres to prevent further fraying. When done well, it’s nearly invisible from both the inside and outside.
Most seamstresses, specialist dry cleaners, or clothing alteration experts offer invisible mending at an affordable price. It’s a small step that can greatly extend the life of your favourite pieces.
