A new story idea every single day.
Ideas can be shit, detailed, loose, tight, scenario-based, character-based, or could just be a single line of dialogue which might later unfurl itself into a glorious tendril of butt-tickling wonder-magic … or something.
Stole this concept from @ryanklindsay.

#247: Bloodlines Shiv
A weapon idea for the London Particular book.
A blade that cuts into your bloodlines. Opens wounds for you and your family. When Snowflake takes a cut on his arm it opens up the disapproving voice of his father (totally taken from a previous story idea but I think it could work in this context too).
