Hello! I’ve been working on this Adult Knit V-Neck Vest from Yarnspirations and it’s been alright so far, but I’m absolutely stumped on the armholes. I’m knitting a large and so I’ve underlined the number of stitches corresponding to that size.

I’ve had no problem casting off and being left with 79 stitches. It’s the next part with the 1st and 2nd row that has me frazzled. No matter how I work it out, I can’t seem to get from 79 stitches to 61 stitches. I keep getting 69. My (obvious) guess is that I’m messing something up in the decreasing but I have no idea what. Thanks in advance!
