I never do much more than scarves with knitting, and really nothing more than knit and purl ribbing, or just plain garter stitch. I've tried to knit cables, and I cant never remember what row I've just done, and still, after three years of knitting, cant tell which side is purl and which side is knit.

At least with crochet, I've been crocheting since I was 6yrs old and it's a heck of a lot easier than knitting. If I want to get something crocheted within a week, I can do that...as long as my hands cooperate.
