I believe that Betsy Ross made the flag because Charles Willson Peale had a painting that showed the flag was in use before the congress chose the design.His other paintings also showed Betsyś flag.George Washington went to her seamstress because Colonel Ross told George Washington about his nieces troubles,and that could have motivated him to let her make the flag. Lastly,Betsy has made flags before.She made Grand Union flags,but the british thought that they were surrendering.So it would make since that George Washington wanted Betsy Ross to make another one.That is why I think Betsy Ross made the flag of the United States.
