When I was a child, my maternal grandmother, Mildred Mae Moore (1898-1981) taught all of us kids how to fold an 8 1/2 x 10 in. piece of paper to make a single cut and end up with a perfect 5 point star. The wtory she told us was about Betsy Ross making the star this way to show Congress how easy it would be to make the stars for the flag.
So, here is a link to a US history site to show you how to make the Betsy Ross 5-point Star with a single cut just like G'ma Moore showed us kids. US History. Org Besty Ross 5-Point Star
With Christmas right around the corner, this is nice to know!
