Also, my step-grandmother pointed out that crocheting products look prettier and more pleasing to the eye than knitted looks. Maybe that's a personal preference, but I am definitely not going back to knitting now that I'm "hooked!" :)
Update: I had a comment on Facebook from my friend, Christina, who mentioned how you have to pay more attention when crocheting than knitting. She said, "Knitting is mindless." I am actually going to agree with that-- I don't have to look at my hands when I'm knitting, so knitting is better if I'm watching a movie. I have to at least glance at my hands when I crochet, although I have a system for when the TV is on -- I can prop my hands on my knees, so they're about eye-level with the screen, and I can make it work!
