I normally use the word "sheet" to indicate "paper". However, does it also refer to blankets as well? If so, could you give me some examples?

Sheets don't refer to blankets, they refer to the very thin layers of cloth that cover the mattress of a bed. They're usually categorize into two types: flat sheets, which just lay naturally on the bed, and fitted sheets, which have an elastic band all around to allow them to adhere to the shape of the mattress better. Ex: Can you change the sheets? There are some fresh sheets in the linen closet. Ex: I spilled coffee on my sheets, so I have to wash them.
