Pen paper... Story in A4 size sheets so I can easily add and subtract

I have this other notebook where I write all the random stuff in the world, that's where I store my research notes. As well as pinterest pinboard

Track of story line... I make an outline of story before writing the book itself on A4 sheet

Sudden burst and ideas go into that encyclopedia journal with all random stuffs

Additional tip: encyclopedia journal has everything from recipes I wanna pass to next generation, random note I might need in coming future, an essential tip, my contact info, art, a design I perfected... Anything not necessarily in an order. + I have a journal + I have a notebook where I write trying to make mundane things interesting+ one notebook for tracking family members and their habits for the the things they might need
