Establishing your own line?

I am reading alot of differing opinions on what it takes to name a line of snake with your name as in NERD line... or Grazi line.....ETC.

*This is mostly to get this information out there*
What exactly does it take to be able to say it's "your line"?

When you prove out an animal that is not associated with any other line (aka a previous morph you have had), you prove out your own line.

For individual morphs, that is true.

However, you can also selectively breed your animals to produce a certain look. Once your animals look noticeably different from the majority of that morph/type, and breed reasonably true, then you should feel free to name your line. (IE, Graziani pastel, or lemon pastel).

lipstick albino boas would be another example of selectivly bred line
