This is for you. I found this at the Mason-Dixon Knit Along site. It is an I-cord Edge for the Warsh Rag. (I know how much you love I-cord edging) This little tutorial gives credit where credit is due.
I admit, I have never tried this technique because it seemed a little daunting to me. But a small project like this seems a good thing to cut my teeth on. Enjoy, Ann!
