Do you have a jumper that’s a little too big for you? Don’t worry, you can shrink it! Shrinking a jumper is a relatively simple process that can be done at home with a few household items. In this article, we’ll walk you through the steps on how to shrink a jumper, so you can get it fitting you perfectly in no time.
Before you start, it’s important to note that not all jumpers can be shrunk. Some materials, such as wool and silk, are very delicate and can be easily damaged if they’re shrunk incorrectly. If you’re not sure whether or not your jumper can be shrunk, it’s always best to err on the side of caution and take it to a professional. However, if you’re confident that your jumper can be shrunk, then read on for the step-by-step instructions.
Identifying the Fabric Type
Before shrinking your jumper, it’s crucial to determine the fabric type to ensure the proper method and avoid damaging the garment. Here’s a detailed guide to help you identify common fabric types:
1. Natural Fibers:
Natural fibers are derived from plants or animals and are generally more delicate than synthetic fibers. Common natural fibers include:
- Cotton: A soft and breathable fabric with good absorbency. It can shrink moderately when exposed to heat.
- Wool: A warm and insulating fabric that can shrink significantly when exposed to high temperatures or agitation.
- Silk: A luxurious and delicate fabric that requires special care. It can shrink gradually over time with regular wear and washing.
2. Synthetic Fibers:
Synthetic fibers are man-made and often possess enhanced durability and wrinkle resistance. Common synthetic fibers include:
- Polyester: A strong and wrinkle-resistant fabric that resists shrinking.
- Nylon: A lightweight and durable fabric that also resists shrinking.
- Spandex: A stretchy and resilient fabric that can shrink slightly when exposed to heat.
3. Blended Fabrics:
Blended fabrics combine natural and synthetic fibers to achieve specific properties. For example, a cotton-polyester blend offers breathability and wrinkle resistance. However, the shrinkage properties of a blended fabric depend on the proportion and type of fibers used.
| Fabric Type | Shrinkage Potential |
|---|---|
| Cotton | Moderate |
| Wool | Significant |
| Silk | Gradual |
| Polyester | Low |
| Nylon | Low |
| Spandex | Slight |
Using a Washing Machine
Shrinking a jumper using a washing machine is a convenient and effective method. Follow these steps to achieve the desired results:
1. Check the Jumper’s Fabric and Label:
Before proceeding, examine the jumper’s fabric and care label. If the material is delicate or prone to damage, it’s advisable to consider alternative methods or consult a professional.
2. Choose Hot Water and a Short Cycle:
Set the washing machine to the hottest temperature recommended for the fabric. Select a short wash cycle to minimize the exposure to hot water and prevent excessive shrinkage.
3. Avoid Using Detergent or Fabric Softener:
These additives can interfere with the shrinking process. Instead, use hot water alone to achieve the desired results.
4. Dry the Jumper on High Heat:
After washing, immediately transfer the jumper to the dryer. Set the dryer to the highest heat setting to further shrink the garment and secure the results.
5. Monitor the Drying Process:
Check the jumper throughout the drying cycle to avoid over-shrinking. Remove it from the dryer when it reaches the desired size or slightly smaller, as the garment may continue to shrink slightly as it cools.
6. Reshape and Iron:
Once the jumper is completely dry, reshape it to its desired form. Use a warm iron to smooth out any wrinkles and set the new shape.
| Fabric Type | Recommended Water Temperature |
|---|---|
| Cotton | 140-160°F (60-70°C) |
| Wool | 80-100°F (27-38°C) |
| Synthetic | 100-120°F (38-49°C) |
Hand Washing
Hand washing is a gentle way to shrink a jumper without using a washing machine. Fill a sink or bathtub with lukewarm water and add a mild detergent. Submerge the jumper and gently agitate it for 10-15 minutes. Rinse the jumper thoroughly with cold water until the water runs clear. Squeeze out excess water without wringing or twisting the fabric.
Soaking
Soaking a jumper in hot water is a more effective way to shrink it than hand washing. Fill a sink or bathtub with very hot water (as hot as your hands can tolerate). Submerge the jumper and let it soak for 30-60 minutes. Stir the jumper occasionally to ensure even shrinkage. After soaking, drain the water and rinse the jumper with cold water.
Reshaping and Drying
Once the jumper has been washed or soaked, it’s important to reshape it and dry it properly to prevent further shrinkage or distortion. Lay the jumper flat on a clean towel and gently stretch it back to its original shape. Avoid hanging the jumper to dry, as this can cause it to stretch and lose its shape. Instead, place the jumper on a flat surface or drying rack and allow it to air dry completely.
| Washing Method | Water Temperature | Soaking Time |
|---|---|---|
| Hand Washing | Lukewarm | 10-15 minutes |
| Soaking | Very hot | 30-60 minutes |
Using a Hairdryer or Iron
Step 1: Prepare the Jumper
Gently wash the jumper by hand or in the washing machine using cold water and a mild detergent. Do not use fabric softener. Rinse thoroughly and gently squeeze out excess water.
Step 2: Drying the Jumper
Place the jumper on a clean towel and roll it up tightly, pressing out as much water as possible. Unroll the towel and lay the jumper flat on a drying rack or clean surface.
Step 3: Applying Heat
If using a hairdryer, hold it 10-15 cm away from the jumper and move it back and forth, concentrating on areas that need shrinking. If using an iron, set it to a low heat setting and press gently on the fabric, avoiding direct contact with the jumper.
Step 4: Reshaping the Jumper
Once the jumper is almost dry, carefully reshape it to its original size and shape. Pull the sleeves, neckline, and hemline gently to stretch and form them. It is important to be patient and work slowly to avoid tearing the fabric.
If the jumper is too small or not shrinking evenly, repeat the drying and reshaping process until you are satisfied with the result.
| Material | Temperature Setting | Drying Time |
|---|---|---|
| Wool | Low | 15-20 minutes |
| Cotton | Medium | 10-15 minutes |
| Polyester | High (but not too hot) | 5-10 minutes |
Steam Shrinking
Step 1: Prepare the jumper
Soak the jumper in hot water for 15 minutes. This will help to relax the fibers and make them more pliable.
Step 2: Steam the jumper
Hang the jumper over a boiling pot of water. Cover the pot with a lid to trap the steam. Steam the jumper for 15 minutes, or until it has shrunk to the desired size.
Step 3: Remove the jumper from the pot
Use tongs to carefully remove the jumper from the pot. Be careful not to touch the hot water or steam.
Step 4: Lay the jumper flat to dry
Lay the jumper flat on a towel to dry. Do not hang the jumper to dry, as this can cause it to stretch out of shape.
Step 5: Iron the jumper (optional)
Once the jumper is dry, you can iron it to remove any wrinkles. Use a low heat setting and press the jumper gently.
Additional Tips:
| Tips to achieve the best shrinking result |
|---|
| Use a natural-fiber jumper, such as wool or cotton. Avoid using synthetic fibers, such as polyester or nylon, as they will not shrink as well. The higher the temperature of the water, the more the jumper will shrink. The longer you steam the jumper, the more it will shrink. Check the jumper regularly to see how much it has shrunk. Once the jumper has reached the desired size, stop steaming it immediately. |
Heat Shrinking
This method is suitable for jumpers made from natural fibers such as wool or cotton. Heat can cause the fibers to shrink, reducing the size of the garment. Here’s how to do it:
Machine-washing
- Turn the jumper inside out to protect the outer layer.
- Set the washing machine to the hottest water temperature recommended for the fabric type.
- Use a gentle cycle and add a mild detergent.
- Run the washing machine through a complete cycle.
- Remove the jumper promptly and do not put it in the dryer.
Lay flat to dry:
- Lay the damp jumper flat on a clean towel or drying rack.
- Smooth out any wrinkles or creases to ensure even shrinkage.
- Weight down the edges of the jumper with heavy objects like books or weights to keep it from stretching.
- Allow the jumper to dry completely at room temperature.
Ironing:
| Fabric Type | Iron Setting |
|---|---|
| Cotton | High |
| Wool | Medium to Low |
Once the jumper is dry, you can iron it to further reduce its size. Set the iron to the appropriate temperature for the fabric type. Iron the jumper inside out to avoid damaging the outer layer. Press down firmly, but do not hold the iron in one spot for too long to prevent scorching.
Using Wool Shrinkage Wash
Wool shrinkage wash is a specifically formulated detergent designed to shrink wool items safely and effectively. Follow these steps to use wool shrinkage wash:
1. Check the Garment’s Care Label
Always refer to the garment’s care label for specific washing instructions and warnings.

3. Dissolve the Wash
Completely dissolve the wool shrinkage wash in the water before adding the garment.
4. Submerge the Garment
Submerge the wool jumper in the wash solution and gently agitate it to remove any air bubbles.
5. Agitate and Check
Gently agitate the jumper for a few minutes and check its progress regularly. If the desired shrinkage is not achieved, continue agitating for a few more minutes.
6. Rinse Thoroughly
Once the desired shrinkage is reached, rinse the jumper thoroughly with cold water to remove any detergent residue.
7. Air Dry
Lay the jumper flat on a clean towel and roll it up to absorb excess water. Do not hang it to dry, as this can stretch the garment. Unroll the jumper and lay it flat on a drying rack or table in a well-ventilated area. Avoid exposing it to direct sunlight or high heat.
Drying the Jumper Properly
Once you have washed your jumper, it’s important to dry it properly in order to prevent it from shrinking or losing its shape. Here are a few tips for drying your jumper properly:
Use a low heat setting
When drying your jumper in the machine, be sure to use a low heat setting. High heat can cause the fibers in the jumper to shrink and lose their shape.
Dry for a short period of time
Don’t over-dry your jumper. Remove it from the dryer while it is still slightly damp to the touch. This will help to prevent it from shrinking.
Air dry
If you can, air dry your jumper instead of putting it in the dryer. This is the gentlest way to dry your jumper and will help to prevent it from shrinking.
Lay the jumper flat to dry
When air drying your jumper, be sure to lay it flat on a towel or drying rack. This will help to prevent it from stretching out of shape.
Reshape the jumper while it is wet
If your jumper does shrink a bit, you can reshape it while it is still wet. Gently stretch the jumper back to its original shape and then lay it flat to dry.
Iron the jumper on a low heat setting
If necessary, you can iron your jumper on a low heat setting to help it regain its shape. Be sure to use a pressing cloth between the iron and the jumper to prevent scorching.
Use a garment steamer
Another option for reshaping your jumper is to use a garment steamer. Simply hold the steamer about 6 inches away from the jumper and gently steam it until it regains its shape.
Stretching and Reshaping
Stretching
Soak the jumper in warm water for 15-30 minutes. Use a mild detergent to remove any dirt or residue. Rinse the jumper thoroughly with cold water.
Gently stretch the jumper in all directions, including lengthwise and widthwise. You can use your hands or a towel to help stretch the fabric. Be careful not to stretch it too much, as this could damage the fibers.
Reshaping
After stretching the jumper, reshape it to your desired size and shape. You can do this by laying the jumper flat on a towel and gently pulling or pushing it into the desired shape.
Once the jumper is in the desired shape, secure it with pins or weights. Allow the jumper to dry completely before wearing it.
Note: Not all jumpers can be shrunk using this method. Some fabrics, such as wool and cashmere, are more susceptible to shrinking than others. Always test a small area of the jumper first to ensure that it does not shrink too much.
| Material | Suitable for Shrinking |
|---|---|
| Cotton | Yes |
| Wool | Yes, but test first |
| Cashmere | Yes, but test first |
| Synthetic | No |
