Shrinking a knit sweater can be a great way to bring new life to an old, oversized sweater or to customize the fit of a sweater that is a bit too loose. Whether you’ve accidentally stretched out a beloved sweater or you’ve found the perfect thrift store find that’s just a bit too big, shrinking a knit sweater is a simple process that can be done at home with just a few steps.
First, it’s important to note that not all knit sweaters can be shrunk. Natural fibers like wool, cashmere, and alpaca are more likely to shrink while synthetic fibers like acrylic and polyester are less likely to shrink or may not shrink at all. Always check the care label on your sweater to determine the fiber content and whether it is safe to try shrinking.
Once you have determined that your sweater can be shrunk, the next step is to prepare it for shrinking. Start by filling a sink or bathtub with warm water and add a small amount of gentle detergent. Place the sweater in the water and let it soak for 10-15 minutes to ensure it is fully saturated. This will help the fibers to shrink evenly.
After the sweater has soaked, remove it from the water and gently squeeze out any excess water. Be careful not to wring or twist the sweater, as this can cause it to stretch or lose its shape. Lay the sweater flat on a clean towel and roll it up, pressing gently to remove even more water.
Now it’s time to start the shrinking process. Preheat your oven to the lowest temperature setting, usually around 200°F (93°C). Place a wire rack on a baking sheet and lay the sweater flat on top of the rack. This will allow air to circulate around the sweater and prevent it from sticking to the baking sheet. Place the baking sheet with the sweater in the oven and let it bake for 10-15 minutes.
Keep a close eye on the sweater while it is in the oven to ensure it doesn’t shrink too much. Every few minutes, check the sweater to see if it has reached your desired size. If the sweater is still too large, continue to bake it for a few more minutes. Once the sweater has reached the desired size, remove it from the oven and let it cool completely before trying it on.
- Read the label: Before attempting to shrink your knit sweater, read the care label to ensure that it can be safely shrunk. Some sweaters may be made from materials that are not suitable for shrinking.
- Test on a small area: Before shrinking the entire sweater, it is advisable to test the process on a small, inconspicuous area. This will help you determine how the sweater will react to the shrinking process without risking damage to the entire garment.
- Have necessary supplies ready: Gather all the supplies you will need for the shrinking process, including a large basin or sink for soaking the sweater, a washing machine or dryer, and any additional tools or products recommended by the sweater manufacturer or other reliable sources.
- Prepare the workspace: Make sure you have a clean and clutter-free workspace to carry out the shrinking process. This will help prevent any accidents or mishaps and ensure that you have enough space to work comfortably.
- Take measurements: Before shrinking the sweater, take measurements of its current size. This will help you track the progress of the shrinking process and ensure that you achieve your desired fit.
- Follow instructions carefully: It is important to carefully follow any instructions provided by the sweater manufacturer or other reliable sources. Different sweaters may require slightly different shrinking techniques, so make sure you are following the specific instructions for your sweater.
Choose the Right Material
When it comes to shrinking a knit sweater, the choice of material is crucial. Different knit materials will react differently to the shrinking process, so it’s important to choose the right type of sweater for your desired results.
- Wool: Wool is known for its natural ability to shrink. If you have a wool sweater that is too large, shrinking it can be an effective solution. However, keep in mind that wool can shrink significantly, so be cautious and take small steps when shrinking wool garments.
- Cotton: Cotton is a versatile fabric that can be shrunk, but it may not shrink as much as wool. Cotton sweaters can still be slightly resized through the shrinking process, but the results may not be as dramatic as with other materials.
- Acrylic: Acrylic is a synthetic material commonly used in knit sweaters. It is less likely to shrink compared to natural fibers like wool or cotton. However, it may still shrink slightly when exposed to high heat or a hot water soak, so proceed with caution when attempting to shrink an acrylic sweater.
- Blends: Many sweaters are made from a blend of materials, such as wool and acrylic or cotton and polyester. In these cases, the shrinking process may be less predictable, as different fibers react differently to heat and moisture. It’s best to consult the care label or test a small area before attempting to shrink a blend sweater.
Remember, the material of the sweater will ultimately determine how much it can be shrunk. Always read and follow the care instructions on the label before attempting to shrink a knit sweater.

- Enjoy Your Shrunken Sweater
Start by trying on the oversized knit sweater and determining how much smaller you would like it to be. Take note of areas that are particularly loose or baggy.
Gently hand wash the sweater using cool water and a mild detergent. Avoid twisting or wringing the sweater, as this can stretch it further. Lay it flat to dry or use a drying rack.
Obtain sewing pins, a sewing needle, and thread that matches the color of the sweater. You may also want to have a sewing machine on hand for larger alterations.
Put the sweater back on and use the sewing pins to secure the areas that need to be taken in. Make sure the fit is comfortable and not too tight. Take off the sweater and carefully pin along the marked areas.
Start sewing along the pinned lines using a sewing machine or a needle and thread. Use a straight stitch for a secure finish. Trim any excess fabric if needed.
Put the sweater back on to check the fit after sewing. Make any necessary adjustments by undoing the stitches and re-pinning the areas that still need to be altered. Repeat the sewing process if required.
To prevent fraying, consider finishing the raw edges of the fabric with a serger or an overcast stitch on the sewing machine. Alternatively, you can use fabric glue or fray check on the cut edges.
Use a steam iron on a low heat setting to gently press the seams and shape the sweater. If the fabric allows, you can also block the sweater by wetting it, reshaping it, and allowing it to dry flat or on a blocking board.
Once the alterations are complete and the sweater has been pressed and blocked, it’s ready to wear. Pair it with your favorite jeans or a skirt for a refreshed and more fitted look.
Step 1: Soak the Sweater
Before you can begin the process of shrinking a knit sweater, it’s important to properly prepare it by soaking it in water. This step is crucial because it allows the fibers of the sweater to absorb water and become more pliable, making it easier to shrink them.
To soak the sweater, follow these steps:
- Fill a bucket or sink with lukewarm water. Avoid using hot water, as it can cause the fibers to become damaged or felted.
- Add a mild detergent to the water and mix well. Use a detergent that is specifically designed for delicate fabrics to ensure the safety of your sweater.
- Submerge the sweater in the water, making sure it is fully saturated. Gently press down on the sweater to ensure that all areas are wet.
- Allow the sweater to soak for at least 30 minutes. This will give the fibers enough time to absorb the water and become flexible.
Note: If your sweater has any specific care instructions, such as dry cleaning only, make sure to follow them accordingly. Some sweaters may not be suitable for soaking and may require a different method of shrinking.
Step 2: Drain and Squeeze
After the soaking process, it’s time to drain and squeeze the excess water out of your knit sweater. Here’s how you can do it:
- Remove the sweater from the sink or basin and hold it gently to let the water drip out. Be careful not to wring or twist the sweater as this can stretch or damage the fabric.
- Lay a clean towel on a flat surface and place the sweater on top of it.
- Gently press down on the sweater to remove more water. You can use your hands or a clean, absorbent towel to do this. Avoid using excessive force as it can misshape the sweater.
- If necessary, you can roll the sweater in the towel and apply light pressure to further squeeze out the water. Repeat this step with a dry towel if needed.
Make sure to remove as much water as possible, but also be gentle to avoid damaging the knit. Once you have drained and squeezed the sweater, you are ready to move on to the next step.
Step 3: Stretch and Shape
After soaking your sweater and removing the excess water, it’s time to stretch and shape it to your desired size.
Here’s how you can do it:
- Lay down a clean towel on a flat surface and place your sweater on top of it.
- Gently stretch the sweater in the areas where you want it to be smaller. This can be the body, sleeves, or both. Pull the fabric in all directions to evenly distribute the stretch.
- Pin the stretched areas with sewing pins. Make sure to place the pins vertically to prevent them from affecting the final shape of the sweater.
- Continue stretching and pinning until you’re satisfied with the size and shape of the sweater.
- If you want a more fitted look, consider using a dress form or a hanger to help maintain the desired shape while the sweater dries.
It’s important to note that the amount of stretching will determine the final size of your sweater. Be careful not to stretch it too much, as it may become too small or lose its original shape.
Once you’ve finished stretching and shaping the sweater, leave it to dry completely. This process may take a couple of days, depending on the thickness of the fabric and the humidity in the air.
Remember to regularly check on the sweater as it dries and make any necessary adjustments. Once it’s fully dry, remove the pins and try on your newly shrunk sweater. Enjoy your customized, well-fitting knitwear!
Step 4: Dry the Sweater
After completing the washing process, it is important to dry the sweater properly to ensure it maintains its new, smaller size. Here are the steps to follow:
Gently squeeze out excess water: Start by carefully squeezing out any excess water from the sweater. Avoid wringing or twisting the fabric as this can damage the knit.
Lay the sweater flat on a clean towel: Find a clean, dry towel and lay it flat on a surface. Then, carefully place the sweater on top of the towel, making sure it lies flat and is not stretched or distorted.
Reshape the sweater: While the sweater is still damp, gently reshape it to its desired size by pulling and stretching it slightly. Pay special attention to the sleeves, neckline, and any areas that need adjustment.
Let the sweater air dry: Allow the sweater to air dry completely on the towel, away from direct heat or sunlight. Avoid hanging it up to dry, as this can cause the sweater to stretch and lose its shape.
Check the size: Once the sweater is completely dry, try it on to ensure it has shrunk to your desired size. If it is still too big, you may need to repeat the shrinking process again.
Following these steps to dry the sweater will help ensure that it maintains its smaller size and shape. Remember to always check the care instructions on the sweater’s label before washing or drying to avoid any potential damage.
If the traditional methods mentioned above don’t work for you, there are a few alternative methods you can try to shrink your knit sweater:
- Use a hot water soak: Fill a basin or sink with hot water and add a small amount of mild detergent. Submerge the sweater in the water and let it soak for about 30 minutes. Gently squeeze out the excess water, then lay the sweater flat on a clean towel and roll it up to remove more moisture. Finally, reshape the sweater to its desired size and lay it flat to dry.
- Try steam blocking: Hang the sweater in a steamy bathroom or use a garment steamer to apply steam to the sweater. Gently stretch the sweater while it is still warm and reshape it to your desired size. Leave the sweater to dry in its stretched position.
- Experiment with a dryer: This method can be risky, but some people have had success in shrinking their knit sweaters by putting them in the dryer on a low heat setting. Check the sweater regularly to prevent over-shrinking, and remove it from the dryer as soon as it reaches the desired size.
- Consult a professional: If you are uncertain about shrinking your sweater yourself, it may be best to take it to a professional tailor or dry cleaner. They can assess the material and help you determine the best method for shrinking your sweater.
Remember, when attempting to shrink a knit sweater, it’s important to be cautious and patient. Some sweaters may not shrink at all, while others may shrink too much. It’s always a good idea to test a small, inconspicuous area of the sweater first before attempting any of these methods.
