My opinion of who made the flag is Betsy Ross. My evidence to prove my opinion is that a famous painter named Charles Willson Peale painted paintings of Betsy Ross making the United States flag in 1776, before Congress approved the flag design. More evidence is that Betsy had her own Seamstress shop and made flags in the past. My last piece of evidence is that there are connections of Betsy and her family. Some of her family members even made notes about what she did.
