How to Un-Shrink a Wool Sweater

Learn how to un-shrink a wool sweater that shrank in the wash with the easy fix in this Howcast video.


How to unshrink a wool sweater. Your favorite sweater wound up in the dryer and is now only fit for a four-year-old? Fix it fast by doing the following.

You will need: Hair conditioner, a flat surface, and two towels.

Step one: Fill your bathroom sink with lukewarm water and 1/3 cup hair conditioner.

Step two: Add the sweater and let it soak for about 10 minutes to unlock the wool fibers.

Step three: Let the water drain, but don't rinse out the sweater. When the sink is empty, gently press the sweater against the basin to remove any excess water. Do not wring it.

Step four: Lay the sweater out flat on an absorbent towel. Put another towel on top of it and press down on it hard to blot out as much water as you can. You can roll the sweater in a towel to remove excess water, as long as you straighten it out again quickly.

Step five: Stretch the sweater back into its original dimensions, known as blocking. This process pulls the unlocked wool fibers away from each other and back into the desired shape.

Step six: Allow it to air dry. Next time you wash it, keep it out of the dryer.

Did you know? Wool is both fire-resistant and, fiber-for-fiber, stronger than steel.
