I know this is going to confuse some people and I don’t want you to be disappointed either way, so I want to clarify. Yes, this is published in an issue of Interweave Crochet which is heavy in Tunisian crochet. And, a lot of you know me for my Tunisian crochet work. But, no, this is not Tunisian crochet. This is regular crochet.
