As others have said, after one wash youÃ¢â‚¬â„¢ll see the elastic start to separate from the main sheet. Even as a cheap sheet- not worth the money since itÃ¢â‚¬â„¢s destroyed after one wash. IÃ¢â‚¬â„¢ll also add that IÃ¢â‚¬â„¢m very intentional when I wash laundry and tend to wash most things on delicate and never dry anything with much heat, so in my opinion this definitely has to do with the quality of the sheet and not how it was washed.
