You’re right. This is working the front of the cardigan. The link to the PDF is below. It is a free pattern from CascadeYarns.com called “Here’s My Heart Cardi”.
I also attached a photo of the cardigan.
Your bind off explanation makes complete sense. However, should I decrease 1 stitch 5 times or should I bind those stitches off as well?
I think where I was getting confused, is if I’m understanding what you’ve written, on the front left side of the sweater, as it’s worn, I would bind off on the Knit rows at the neck edge and bind off on the Purl rows at the arms.
Then, for the front right side of the sweater as it’s worn, I would bind off on the Knit rows at the arms and bind off on the Purl rows at the neck.
Am I understanding that correctly?
