This is my humble attempt at reproducing the scarf worn by the character Rose Tyler from Doctor Who. She is seen wearing the scarf in the episode Boom Town.
I used 4 colors of a variegated yarn, with 2 of the 4 different colors held double. Only changing 1 color at the end of a chart repeat.
This pattern is basically just a chart, it can be repeated as few or as many times as wanted to the desired length.
