Aisalynn Writes

Is there a way to change the format of your journal for a single post? Like, when you see it on my journal it's in my normal layout, but when you click the cut, it's that plain white format? I'm just wondering because the SPN/J2 Big Bang deadline is coming (and though, thanks to my hypothyroidism and that damn Synthroid I'm behind and really cramming in the writing this last week, I'm determined to get it done.) and I'd like to just have the plain white background for the story when it comes time for me to post it.

I've seen it this way on other people's journals, but I have no idea how to do it. Can anyone help me?
