How to Unshrink a Merino Wool Jumper

Merino wool jumpers are cherished for their softness, warmth, and breathability. However, they can sometimes shrink if not cared for properly. This is because merino wool fibres have microscopic scales that interlock under heat, moisture, and movement, causing shrinkage when washed or dried incorrectly. If you have accidentally shrunk your merino wool jumper, here is a step by step guide to help you unshrink it.

Materials Needed to Unshrink

• Lukewarm water
• Mild baby shampoo or conditioner
• Large towel
• Flat surface for drying

Steps to Unshrink

1. Fill a basin with lukewarm water. Avoid using hot water, as it can further shrink the wool.
2. Add mild baby shampoo or conditioner. This helps to relax the wool fibres, making them easier to stretch.
3. Soak the jumper. Submerge the shrunken jumper in the water and gently swish it around. Let it soak for about 30 minutes.
4. Gently squeeze out excess water without wringing or twisting the jumper. Lay it flat on a large towel and roll the towel up to absorb more water.
5. Reshape the jumper. Carefully stretch it back to its original size and shape. Be gentle to avoid damaging the fibres.
6. Dry flat on a clean, dry towel on a flat surface. Allow it to air dry completely, reshaping as needed during drying.

How to Shrink a Merino Wool Jumper

If you need to shrink a merino wool jumper to achieve a better fit, you can do so carefully.

Materials Needed to Shrink

• Washing machine
• Dryer
• Mild detergent

Steps to Shrink

1. Wash in warm water. Place the jumper in the washing machine and set it to a warm water cycle. Use a mild detergent suitable for wool.
2. Check the jumper after the wash cycle to see if it has shrunk to your desired size.
3. Dry on low heat. Place the jumper in the dryer and set it to a low heat setting. Check periodically to ensure it does not shrink too much.
4. Reshape as needed. Once the jumper has shrunk to your desired size, remove it from the dryer and reshape it while still slightly damp. Lay it flat to finish drying.

Tips for Caring for Merino Wool Jumpers

• Hand wash whenever possible in cold water with a mild wool detergent.
• Avoid exposing your jumper to high heat, as it can cause shrinkage.
• Always dry flat on a towel to maintain shape and prevent stretching.
