How do you weave in the ends of knitting?

Should you block knitting before weaving in ends?

Here’s my rationale: you need to wash and block pieces before you sew up, and since—see below—a seam is my favorite place to weave in an end, you need to have seamed the garment. Also, if you weave before washing and blocking, and the fabric relaxes, it can result in a pucker or bunch in the fabric.
