Yes, knitting is definitely better for clothing. It's not so hole-y. Crochet is more for decorative stuff, and for things like vests or stylish hats that don't need to keep you warm. This is why it opens up the whole world of yarn crafts for you if you can do both, which is what I keep trying to tell my mom. She tried crochet but gave it up, saying she hated it. When I told her you were learning to crochet, it made her think about maybe trying it again!

Ohhh, that book looks awesome! It's true, a lot of projects can use both styles and end up really pretty and exotic-looking. :)
