Using this vintage 1940s linen and hemp sheet is simple. Just put it on your bed as you would with any regular sheet. Since it might have age - related marks, if you want to clean them, you can wash it at 40 degrees Celsius. Make sure to iron it while it's still a bit damp, as this may help remove the marks. But be gentle when handling it because of its age. Store it in a dry and cool place to keep it in good condition for a long time.
