Zig Zag Chevron Vest

I originally designed this V-neck vest for my Level 2 Master Knitting program submission and made it in a size small, with the neck trim kissing at the center front. After making it in a size medium, I discovered that adding the extra repeat of the pattern made the chevron point down at the center front instead of up, so I adjusted the pattern to include instructions for a crossover V-neck trim as well, so that the neck trim did not distort the chevron body pattern on sizes M and XL.
