Ahhh! So you've been bitten by the crochet bug, eh? Nothing wrong with that. It's a great craft to learn! You'll probably pick it up quickly since you seem to have taken to knitting so well.
I actually crochet a lot faster than I knit, but there are those who disagree with me for sure. And rather than thinking of this as adding more hobbies to your already busy life, consider it as adding new tools to the toolbox--it's always handy to know how to do something in more than one way!
