It is a bargello, so it shouldn't be that hard to draft. I made a similar one in a class, but we just followed directions - no pattern. If you have a flag handy, you can figure out the proportion of the area for the stars and the stripes. The stars will be a square, the stripes look to be 2.5" strips. My stars were not cut in the bargello, just the stripes. Can't lay my hands on the flag right now, but we made it in 4 hours.
Just found this link -- the original pattern is gone.
