I love a soft woolen sweater as much as the next one. But I can’t stand burls. Which is unfortunate since woolen clothes get these in matter of a couple of wears. So, one day I sat myself down at the floor and started working on it (this works on clothes that are other materials as well).
This is how
1. Look at the cardigan and identify all places with burls.
2. Take your racer and use preferably a new blade. Shave at all places with burls.
3. Use a lint roller to remove the, now loose, burls (you don’t want them in the washer). After this step it’s easy to see if you missed a spot and need to go for another round.
4. After this, you wash the cardigan and voilà. It’s as good as new!
