Back before I had to stop doing crochet because of my wrists, I was fascinated by slip-stitch crochet/pjoning. It turns out that if you work it at a much looser gauge, slip stitch crochet is actually fairly stretchy and has good drape, rather like knitting. Use a much bigger hook than you ordinarily would for crochet.
Here is a pair of socks I made with a pjoning hook. I wore them out and loved them. http://ravel.me/gannet/yb8sx
@gannet oh WOW, those designs are gorgeous! I've never seen crochet like that!
@pursuitofnerdiness you can see why I was fascinated (and rather miffed when I had to stop crocheting)!
