I don't see any stains. One side of this is not cut completely straight but kind of wavy. I took the length measurement from what I thought to be the shortest spot but I could have misjudged. See pics. On that spot it was a tad more than 86" less than 87" according to my tape. I haven't judged the width let me know if you need me too. This would perfect to use as a table covering or backdrop to sell cookies.
