Ok, so first off! A tip that I started doing quite a while ago, and it really works for me.

Pinterest!

I know some of you guys are like what? That's it? Yes, just use Pinterest for everything!

I literally use it to collect potential covers, outfits, story ideas and details, weapon art, and even just plain art.

Pinterest is a great way to keep a story organized, and helps me collect my thoughts so I'm not going insane to remember everything and keep it in my head.
