From the Stitch Description: The advantage in using three different colors of yarn in a color-contrast pattern is that the color may be changed on every row without cutting or braking any of the strands. Color A takes you across again to Color A, and so on. There are two methods of doing this stripe pattern, either of which may be used alone, or they may be combined - 12 rows of Woven Method, then 12 rows of Stranded Method, etc. - for an even fancier effect.
