Lots of knitters pick up stitches by grabbing a strand of yarn along the edge of their knitting and putting that strand on their needle as a stitch. This is not how picking up stitches is taught by most sources and will not work when you need to pick up more than one stitch per row of knitting.
I learned from expert sources many years ago how to pick up stitches neatly, without distorting the edge of your knitting. For this pattern, you need a large number of stitches for the front band, so that the front of the sweater does not pull up, but makes a nice curve.
Below are some photos of one way to pick up 2 stitches in one row.
I have used a contrast color yarn so that the stitches picked up are easy to see.
