I think  Betsy Ross made the first American flag  .  She had flag making experiences and owned a shop . Another reason I think   Betsy Ross made the first American flag  was the fact that they  found one of her stars in Samuel Wetherill’s safe.  The star has been in his safe since 1776 , which was the year that Colonel Ross  and George Washington came into Besty’s  shop .  I just think it was coincidental for so much to happen in such a short time period .
