Many knitters use this method for neat and straight vertical edges of their work (including myself)
Most crocheters love making stuff composed of motifs such as granny squares. I'd say all crocheters love motifs, but I typically try to avoid generalizations, as there might be a dozen of those who don't like composing big things out of small ones. And I bet it's mostly because of the "cut yarn, weave in end" part that happens too often. And here comes this technique that helps you remove the "cut yarn" from the formula.

In this tutorial, I'll describe continuous joining of crochet motifs used in most of my patterns. Motifs are joined together using the join-as-you-go (JAYGO) method as you work their last row or round, no sewing required.
