When to use Whip Stitch for Joining Crochet?

Whip stitch is a visible stitch with some seam stretch. It creates a diagonal bar which is nicely decorative. With the same coloured yarn as the squares/ panels being joined, it looks like part of the stitch detail and therefore invisible. With a contrast colour, it adds a candy-stripe effect along the join lines.
