A drawstring secured fitted sheet where the corners are fashioned to avoid binding the string. It has a hem that holds the drawstring that is fabricated separately to allow that the edges of the sheet can be curved. The hem is terminated short of closing to allow a gap for the drawstring to exit. A stiffener is added at the gap to hold it open. There can be a block or pulley added to aid in tightening. |
