I think Betsey Ross designed the flag,because there is more proof and stories behind her making the flag than Francis Hopkinson,he did have a receipt but it was revoked the first time,and the second receipt for a naval flag.Also,in the historical society meeting William Canby told a story where a girl named Hannah Whetherhill got a 5 pointed star from Betsey Ross and it was found in a Whetherhill safe. S that is what I think but  could be wrong because no one knows who exactly made the flag.
