If I am correct, these two projects are the same pattern by Birchbark (Russell) with
entirely different results. One was cut an about an 18.5 degree angle and the
other was cut with no angle and the rings alternated.
Now I guess Birchbark will have to tell us which was his intended results or
intended cutting method when he designed the pattern! LOL
