craftgrrl | Joining Granny Squares?

hi hi.

I started to crochet granny squares and I'm wondering how to join them. I've gone to you tube, and there were two videos: How to join them using a contrasting yarn, and how to join them as you go.

I'd like to join them as I go, but the video for that wasn't very helpful since the two squares were half way joined (with out showing me the beginning) so again...that wasn't terribly helpful.

If any one knows how to join them as you go, that would be great, I'm more interested in that than using a contrasting yarn (which I'll try next time)

For any one else who doesn't know how to crochet granny squares , I learned how to crochet them from this series of you tube videos here : http://www.youtube.com/user/Bethintx1#play/user/7AC5730A7D576011
