Factors to Consider Before Shrinking Woolen Clothes

Before attempting to shrink woolen clothes, it’s important to consider several factors to ensure successful and satisfactory results. Here are some key factors to keep in mind:

  • Fiber Type: Different types of wool have varying shrinkage properties. Some wool fibers, like Merino, may not shrink significantly, while others, such as Shetland or Lambswool, have higher shrinkage potential. Research the specific type of wool you are working with to understand its shrinkage characteristics.
  • Garment Construction: Consider the construction of the garment. Some woolen clothes have been pre-shrunk or treated to prevent shrinkage. Check the garment label or manufacturer’s instructions to determine if the garment has any special treatments or considerations regarding shrinking.
  • Desired Shrinkage: Determine the amount of shrinkage you desire before proceeding. Measure the garment and compare it to the desired size. Keep in mind that wool can shrink unevenly or become distorted during the process, so consider the final fit and shape you want to achieve.
  • Test Shrinkage: Before shrinking the entire garment, it’s advisable to conduct a test on a small, inconspicuous area. Cut a swatch or choose an inside seam to shrink as a sample. This will help you assess the potential shrinkage and make any necessary adjustments before treating the entire garment.
  • Method Selection: Consider the shrinking method you intend to use. Common methods include washing in hot water, applying steam, or using a dryer on high heat. Each method may have different levels of effectiveness and risks, so choose the most suitable method for your garment and desired results.
  • Risk Assessment: Understand that shrinking woolen clothes can result in irreversible changes, such as excessive shrinkage, distortion, or damage to the garment. Assess the risk versus reward before proceeding, and be prepared for the possibility of unintended outcomes.
  • Professional Assistance: If you are uncertain about shrinking the garment yourself, or if it is valuable or delicate, it may be wise to seek the assistance of a professional cleaner or tailor who specializes in wool garments. They have the expertise to handle the process properly and minimize potential risks.

Different Methods to Shrink Woolen Clothes

There are several methods you can try to shrink woolen clothes, but it’s important to note that shrinking wool can be unpredictable and may result in irreversible changes. Here are some common methods:

  • Hot Water Wash: Fill a basin or sink with hot water, ensuring it’s not boiling. Submerge the garment and let it soak for about 30 minutes. Gently agitate the garment to encourage shrinkage.
  • Rinse with cold water, then press out excess water without wringing. Reshape the garment to the desired size while damp and allow it to air dry.
  • Steam: Steam can help shrink wool without submerging it in water. Hang the garment in a bathroom while taking a hot shower, or use a handheld garment steamer. Hold the steamer a few inches away from the fabric and steam it evenly, focusing on the areas that need shrinking. After steaming, gently stretch the garment to the desired size and let it air dry.
  • Dryer Method: Place the woolen garment in a dryer on high heat. Add a few dry towels to aid in the shrinking process. Monitor the garment closely, checking its size periodically. Remove the garment from the dryer and reshape it while still warm, stretching it to the desired size. Let it air dry completely to retain the achieved shrinkage.
  • Boiling Method (Extreme): This method carries a higher risk of excessive shrinkage or damage. Fill a large pot with water and bring it to a boil. Submerge the garment in the boiling water and agitate it gently. Keep a close eye on the garment and periodically check its size. Once it has reached the desired shrinkage, remove it from the water, press out excess water, and reshape while damp. Let it air dry completely.


In conclusion, shrinking woolen clothes can be a challenging process with unpredictable results. It is important to carefully consider factors such as the type of wool, garment construction, desired shrinkage, and the chosen method. Testing a small area before treating the entire garment is recommended to assess potential shrinkage and make adjustments as needed.
