I saw it dozens of times in anime, and as i read that cabal grimoire recently,
i thought again about: buying a stash of sticky notes -> consecrating (somehow) of the whole stash, and write some sigils on one block -with a drop of blood on every single sheet,
The prepared one would be carried around all time, along with a consecrated but blank block, a marker, something to draw blood with, needle and string, and blank un-consecrated pages.
Any idea how to start this?
EDIT: Alternatives would be, so sit for a damn hour, and to cut out preprinted sigils.
So in case of use, they would be allready consecrated, but would only need some yummy red stuff and to draw arcoss the lines before doing anything.
