Pavloposadsky woolen shawls will serve you for many years if you treat them properly.
They are made of pure wool. You cannot wash or bleach them, as well as dry in the drum of a washing machine, as it will lead to the deformation of the fabric. If your scarf gets dirty-give it to the dry cleaners.
But if you get caught in rain or sleet in your shawl, it is recommended that you shake the shawl and dry it on a flat surface, having enclosed under it absorbing material, or iron through a cotton cloth.
