Okay, i made a batch of icons using colouring based on a tutorial i saw here. Now i've been asked to write a tut but i cannot find the colouring tutorial to link to so i can credit the person who wrote the original tut!!

I've searched through 2 months worth of posts and cannot find the tutorial so i was hoping someone would have a link to it.

Here are the original images used in the tut:

Any help will be very much appreciated!! :)
