What is your writing process like?

I'm curious to all the writers out there what your process is like? For me I have a bunch of ideas, images, phrases, character tags and other mental detritus that I accumulate on post-it notes that keep popping out of my pockets and am somehow supposed to string together like words from a crossword puzzle into a novel. I guess for me writing is something akin to piecing together a patchwork quilt. What is your take on things?
