This pattern was inspired by the book Sequence Knitting by Cecelia Campochiaro. By repeating a very simple sequence (K3, P1) and introducing a second color, you create what appears to be a very complicated pattern but is actually quite simple.
A Latvian braid pattern enhances the beginning and end of the pattern.
