Circular yokes are ideal for continuous texture and color patterns. The striped pattern shown here is based on the Fibonacci number series, with each number of the series dictating the number of rounds in the stripes. To blur the lines between stripes and add a bit of texture, a slip-stitch pattern is worked on the first round at each color change. Narrow stripes of pattern also decorate the lower body and sleeves, just above a ribbed edging.
The worsted yarn used here looks best knitted at 4.5 stitches/inch, which is not a gauge that appears in the standard tables. To get the desired size, I followed the stitch numbers in The Knitter’s Handy Book of Sweater Patterns for a gauge of 5 stitches/inch in a circumference 4” (10 cm), or two sizes, smaller than desired. I used the length measurements for the desired size.
