Relax! It is possible to unshrink wool that someone (not you, of course) popped into the dryer and is now small enough for little Bruiser to wear.
And pretty much all you'll need to do is help your sweater fibers relax, too, with a little help from baby shampoo worked gently into the fibers while washing it by hand.
The most time-consuming part: Pinning, stretching and pinning again, to gently unshrink wool to return your sweater to its original size as it dries.
Here's how to get the resizing process started.
To unshrink wool, start by soaking the sweater in a sink or bucket full of warm water and about two tablespoons baby shampoo.
This soapy soak serves to relax natural fibers such as wool so that you can gently pull it back into shape without breaking any of the wool fibers.
About 15 minutes should be long enough for the wool garment to relax and soak.
Remove the wool garment from the soapy water, rinse under cool running water.
Remove as much of the water as possible by gently squeezing the wool garment starting at the top and working your way down.
Resist the urge to wring - that can cause the wool fibers to break.
To remove any lingering moisture from the wool before you begin the letting out process, roll the garment in a towel.
Pin the sweater to a large cork board, stretching the neck, arms, and sides as taut as possible without damaging the fibers. Let it be for at least an hour.
Return to re-stretch and re-pin your sweater every few hours. It will take several stretching and re-pinning sessions to unshrink wool.
But if you adore that wool garment, you'll be delighted with the results of your unshrinking efforts. And if needed, consider a how to wash clothes refresher course.
