Crocheting without Crocheting

Crocheting without Crocheting is the title of this article in the April Newsletter of Jimmy Beans Wool. And I don't have any idea what they're talking about. Oh, I do know what they're doing, they're crocheting. Adding a single crochet edge to a knit square, to be exact. But what are they Talking about? They're crocheting! Why do they say without crocheting? How do they think they're crocheting without crocheting? Is this some kind of magical wording so that knitters who despise crochet won't have to admit that that is what they're doing? Is it to keep these same knitters calm? "Just relax, you can do it, it's not really that impossible craft of crocheting that's too difficult for you as a knitter".

In the meantime, I'm leaving the computer to do some crocheting with crocheting, using crochet hooks.
