Okay so I'm finishing my very first knitting project.

We won't talk about how it's about time...I've been teaching myself to knit off an on (mostly off

) for the past couple of years. Anyway, I realized earlier this week that it's my mother's birthday on the 15th, and I didn't have a gift for her. So....I decided to

her a scarf.
I finished in many hours more than it should have taken me, but at least I finished it and didn't frog the whole thing.
So I've bound off, and my question now is how to weave in my ends. I am trying to do this with a crochet needle (and no crocheting background to speak of) as I don't have a needle that would work.
I'm sure it's very easy, but I need someone to explain it to me or point me to a source that can show me. I tried knittinghelp.com but couldn't find anything.
