The flax comes from France. The cotton is grown n Bulgaria and the fabric is made here as well. The climate in Bulgaria is dryer and colder than the climate in other countries, where cotton is usually grown. This is the reason the cotton here is not attacked by insects and diseases, so it is not treated with any chemicals. The only pest that occasionally attacks the cotton here is aphid (plant-louse), but it is left untreated.
Wash at gentle cycle with a mild detergent, without brighteners. This is a natural fabric so it will wrinkle when washed.
