Picking up stiches on edge of sweater

I’m making a baby sweater and it tells you to pick up stiches. How do you do that and make it look nice. Thanks

Here’s a video that will help. I’ve found that as long as you pick up along a column of sts or across a row, the results look quite good. The spacing doesn’t have to be precisely even, approximayely works well.

Thanks!
