How to get the texture template(?)

So, I’ve watched videos on people having this template of their work? Like it has all the faces of their work so they can do more things with the texturing? How do you find this? I’m new to Blender, just made my first model, which was a sword and really want to texture it to the best I can.

Huh? Sorry, but it remains completely unclear what you’re talking about. Please post a screenshot of this “texture template”…
Or are you talking about UV coordinates? If so, you might want to search for “UV unwrapping” in this forum.

UV Unwrap the object then in the UV/Image Editor window you can use the ‘UVs / Export UV Layout’ menu to save the layout in either an image or vector format for painting in an external application.
