I didn’t use a pattern, just free-handed it.

 I say its unfinished because I would like to put stars.   Not sure if I like it enough to finish it though.    You can see it has two sides, I thought one little bit of blue and lots of red and white stripes just didn’t look right.  If you couldn’t see the blue part you wouldn’t get it was a flag.  The silver line it supposed to be a flag pole.
