This pattern is, alas, not free. But you just have to see it. I am considering making it for myself, out of the EXPENSIVE yarn that it would take. I just think this is glorious. It's called the Infinity Wrap, and it's by a fabulous designer named Kristin Omdahl. Take a gander:
And you can buy the pattern here, on Interweave Crochet. Which, by the way, is an absolutely fantastic crochet magazine, with some really beautiful patterns.
I'm really thinking about this one, but my queue of work "to be done" is way too long already.......
