Layering lushness

When I write a first draft, the words pour out.
I know my characters: what drives them, where they want to go, where they'll be at the end of the story.

How they get there? Well, that's the fun of sitting down and just writing.

I'm almost at the end of my current WIP and stumbled across a whole load of pics I'd researched at the start for my vintage heroine.

They are so evocative, they instantly add richness to the story.
I'm going to use these pics while I layer during my next draft.

Which got me thinking...all you writers out there, how do you layer?
