Thanks once again, M-R. This was a whole new world for me. I’d never though about crochet entrelac before. I watched most of this video which looks more like Tunisian crochet:
I don’t see a good way around stitch by stitch frogging for an entire row, assuming this is similar to the method you used. I’ll be interested in what someone with experience in the technique has to say. If nothing else maybe an email to Mikey at the Crochet Crowd would help?
