Before picking up stitches, find the edge stitches and decide which side of the work should be visible. A smooth edge usually offers a consistent column to work along.
You rarely need one new stitch for every row. Use the project instructions as your starting ratio, then distribute the pickup points evenly across the edge. Mark key positions first if the section is long.
Work with a needle size that gives you a flexible edge. If the first attempt feels puckered or too loose, it is worth trying again before continuing the collar or button band.
