How to wash wool garments?

Handwash your wool garment, in cold water, gently, without rubbing or wringing it. You can use your own hair shampoo as a detergent! Add a few drops of white vinegar to the water of the final rinse water.
To dry your wool garment, roll it in a dry towel or spread it between two towels and roll it with a rolling pin.
Then lay your sweater out flat, on a dry towel.
Wool garments do not need to be washed each time they are worn. Often, airing them out for 24h will be enough to refresh them.
