Hair braiding techniques

I`m looking for hair braiding techniques that are safe, creative and has variety. Just wondering if anyone can share their talent by sending me instructions on how do it. I know that there are schools out there but in Canada, they are not very experienced and no one shares their secret.

I am specifically looking for instructions on hair braiding with extensions, including other designs such as cornrow, dreadlocks, weaving etc.

If you know someone or if you can direct me as to where i may find an instructional video, it would be very helpful. Thanks!
