What are the creases, exactly?

I haven’t folded my sheets. They have creases now. I try to stretch the material, but the creases don’t go away by simply trying to tense it up. You can remove them though if you iron the sheets, and it’s easier if you use steam. How come? Is it just compressed and steam allows it to decompress more easily?

Wrinkles and creases work the same way. They’re usually formed by heat. The fibers that make up your sheets are weaker when they’re warm and so more malleable. (Think like beeswax, warmed up in your hands) They can be misshapen, when the fabric cools down they are inclined to stay in that position.

Ironing just warms it up again and weakens it again.
