Vests are always fun to knit because you are done so quickly - no sleeves to make! This one goes especially fast with heavy worsted weight yarn. The vertical lines on the bottom section are achieved by knitting side to side. The top sections are picked up and knit in the usual direction. We have seen this vest knit in both solid and multicolored yarn. Both versions are great.
