Instructions:

All our cotton bed linen can be washed on a light programme up to 40°C.
Use a moderate and not strong detergent - preferably liquid - for cotton fabrics. Do not use bleach Remove the sheets as soon as the washing machine is finished. This way you will avoid wrinkles and also problems with spots/bleaching from contact with other clothes.
Drying

Prefer natural drying. There is the option of tumble drying in the corresponding program. (Do not dry them naturally in strong sunlight or in a dryer at a moderate temperature)
Iron

Iron at a medium to high temperature.
Storage

For storage, prefer fabric cases that allow your bedding to breathe and keep it in a dry place.
For long term storage (over 3 months) it is very important to wash, dry, iron and store them in a cotton bag.
