Cotton, a natural vegetable fiber from the seed pod of the cotton plant, can be a fickle fabric. Due to cotton's tendency to expand when wet and shrink as it dries, most everyone has a tale to tell of cotton catastrophes in the laundry room, from shrunken shirts to too-tight jeans. Occasionally though, a person may need to shrink a cotton fabric on purpose. Luckily there are a couple of simple ways to achieve that goal.

    Be sure that your fabric is 100% cotton . Realize that the shrinking process is permanent, so make sure you really want to shrink the item on which you are using this method.
    • If the tag says "preshrunk," your efforts may or may not be in vain. Give it a try, but know that any shrinking method won't be as effective. It could also shrink in certain places and not in others. Worth a shot?

    Since a bit of color loss may happen, it's important to shrink your items separately (unless they're the same color, of course). You may wish to stir the fabric with a wooden spoon to ensure that it is completely soaked.
    • If you only want your item to shrink a bit, bring the water to a rolling boil, take it off the burner, and wait 5 minutes before you put your shirt in. The longer you wait, the less it'll shrink. Put directly into the water it can shrink up to 2 sizes.

    Again, be sure your fabric is 100% cotton and that you actually want it shrunk. If it's not 100%, it could still shrink -- just probably not as much.
    • If it's 100% cotton but "preshrunk," you'll need to weigh your options. It's possible it won't shrink it all, that it'll shrink only in certain places, or that it'll shrink just fine.
  2. Watermark wikiHow to Shrink Cotton Fabrics
    Do not run the washer with other clothing or fabrics that do not need to be shrunk or that might bleed in the wash. In hot temperatures, colors are more likely to bleed, so it's best to avoid the possibility.

    Some people recommend adding an enzyme solution to the wash, but this has not been verified. However, you may add a cup of white vinegar if you're concerned with color loss.

    Once more, set the dryer to the highest possible heat setting and wait until your fabric is completely dry. If you want it to only shrink 1/2 - 1 size, however, consider checking on it halfway through. You don't want to shrink it too much!
    • A nice, woven cotton dress shirt will shrink anywhere from 1-3%. Doesn't sound like much, but a 35" arm means about 1" will disappear! [5]

  • Question
    I do not have a dryer. Can I shrink cotton by hanging it outside?
    Community Answer
    Clothes dryers shrink cotton through the use of heat. Hanging cotton fabric outside to shrink it will not be successful, because the temperature is not high enough to cause shrinkage.
  • Question
    How do I shrink Baumwolle, which has a slightly different texture and may respond differently than cotton derived from the cotton plant?
    Community Answer
    Why do you think it is different? "Baumwolle" is simply the German word for cotton. There is no difference in the origin of the material.
  • Question
    I have an expensive pair of cotton jeans I need to shrink an inch or two. Does boiling for five to 10 minutes damage cotton?
    Community Answer
    Yes and no. All laundry damages the fiber. All wearing damages the fiber. Bug, the process of shrinking itself won't damage the fiber more than putting it through a normal laundry load three or four times. Be careful about any hot-fix embellishments (like any stones or studs that are glued on), because those can fall off when you shrink, even on expensive jeans.
