Contemplating the frog

No, no, not frog used as a verb, frog as a noun. I have finished the cape for the fall issue of Knit.1 and am thinking of frogs as closures. Long ago, in the first piece I ever designed (which, in retrospect, was (O)VER(L)Y ambitious -- pleat, frog with crochet-covered button, shawl collar) I used a frog designed by the wonderful Nicky Epstein. It involved knitting I-cord and then contorting it into the correct shape using a diagram and tacking it down into place. It was fairly complicated. This is the original frog. Recently I did a simpler frog when I knit a Rowan pattern (in the Autumn/Winter 2006 issue #40). For this one, the instructions were to single crochet a length of yarn. There was not much twisting and no tucking, just tacking. I need something a little more angular for this job. I'm looking to match the diamond border. I think I'm going with I-cord and a simpler construction, as there will probably be three (or possibly four) frogs. I'll let you know how it turns out.
