Flux and flow is a term used by Brian Froud, who is a mythographer and painter. He describes faeries' favorite times as anytime "betwixt and inbetween or transitional."
He uses it most strikingly in the following excerpt:

“[Faeries] inhabit transitional spaces like the bottom of the garden: existing in the boundary between cultivation and wilderness. Or at the edges of water, the spot that is neither land nor lake, neither path nor pond. They relish moments of 'flux and flow': the hush between night and day, the times of change between one season and the next. They come when we are half-asleep. They come at moments when we least expect them; when our rational mind balances with the fluid irrational."

I’m sure faeries aren’t the only ones who love transitional times--in fact, I’m sure that you the reader loves those times as well. Times like twilight, sunset, or when the fog begins to settle in the morning. Times like that.

Like many, I always wanted to be taken away by mythical creatures or make friends with the faeries living in my backyard, but they don’t invite so easily. And perhaps as a coping mechanism, I loved to see scenes that I imagined faeries would habit. Many times, it was about finding a story to be told.

This section of the thesis is really about strapping on those training wheels now. Your first task is to find faeries in the flux and flow of time. Take that time to search and imagine. Take that time to readjust your perspective and look in the crevices you’d otherwise ignore.

Take a breather.

I took the pictures on the right with thoughts of living my fairy tale dream, or imagining what kind of mythical creatures could be living in their shadows. Pretty romantic right? Kinda sappy.
