Hair extentions how do I learn how to make them?

I wanted to learn how to make your own hair extentions weafs out of bulk hair but have no clue where to start does some one have any advice or perhaps a link to a website that could help me out?

First go buy the clips for it - trust me they are SO much better than the glue. I've done the glue ones and its such a mess. Making the clip in ones are simple and work great. Even awesome how you can take them out whenever you want. These ones will last longer.

I found a video on youtube.com of a girl showing exactly how I did mine:
