Color on the Side Jacket

Worked from cuff to cuff with asymmetrical front and I-cord borders. This is an easy to knit jacket that is a natural for self striping yarns.
Uses heavy worsted weight (chunky) #5 yarns.  Gauge given is 16s = 4" on size 8 (5mm) needles.
3 sizes with finished measurements of 42" (46", 50") take 1100 (1250, 1400) yards main color, and about 100 yards contrast color in DK/light worsted weight yarn.
