You know, this is amazing. Is there even a small chance of you making a tutorial sometime in the near or distant future? Because if there is, you just made my day.
Wowsa, that's great! Oh, and don't worry, I'm sure it takes time to develop a clear method. I don't have one either. Just make sure that you don't forget any of the important techniques for what you have done so far, that would be a great shame!
I will think about a tutorial but actually I don't have any clear and well-defined method ... I'm still trying to find one
