I think that Betsy Ross made the first American flag. For one thing, we know that she made a wonderful five pointed star with just one snip of her scissors, and the American flag has five pointed stars. Because she worked in a upholstery shop, she often made flags. George Washington knew her because they went to the same church, so it was likely he arranged a meeting with her. That is why I think that Betsy Ross made the first American flag.
