Needles: #9 (5.5mm)
Pattern: "Valour" by Sarah Hatton from the Colourscape Chunky Collection
Comments: My modifications were to not do the ribbing in the original pattern, but to do the vest in mostly stockinette. I love the way the colors change and thought they were even more interesting in a stockinette pattern.
As you can see below, the armholes are treated in an unusual fashion. And since I picked up only the edge of the stitch on the sleeve opening, it shows the other part of that stitch, which I like a lot.
The seams were sewn up with a fingering weight yarn.
