How do i UV map?
NO 64bit blender! 32 only!
Make sure its detailed

Dude... You keep asking the same question, and expect different answers.

Modeling and UVMapping are hard work, especially at the beginning.
You are going to have to sit down, and slog through some boringly simple tutorials until you learn how it works. Then you apply that knowledge to your project.

I also had difficulties with UV mapping, but I succeed with these two vids:

I mapped a leaf just like the one in the first vid, but I don't know how complicated your shape is. Hope this helps!

Btw, first vid is with an older version of Blender, but things work the same. Feel free to ask about functions in this video. I'm totally new to it, but found out all the functions he's talking about.
