Patchwork and Quilting - how to write a short story

Just recently I have been writing short stories (Lankaren is taking a rest) and I have realised I make stories in much the same way I make fabric art. That is, I save little scraps of this and that and look for ways they work together to create an overall "something" that is more than the sum of its parts. I suppose all art is like this - the juxtaposition of pieces that contrast and reflect on each other - creating a resonance between them that is a whole new thing.
A writing friend once described her way of writing as casting a fishing line into a pond and pulling something out which had something else tangled in it, and that something else had something else dangling off it ... in a little string of things that together made a story - not just a sequence of events, but also details that when added together give the story depth and richness and truth. So for example a character loves shoes - this fixation is both a detail of character and a device by which ideas about materialism, luxury, the Cinderella myth and even political comment (Imelda Marcos anyone?) can be explored.
I have also been reading about writing again - including Writing from the Inside Out, by Dennis Palumbo (a therapist who specialises in creative issues - only in America!) and Negotiating with the Dead by Margaret Atwood. Palumbo manages to be both encouraging ("you are enough") and depressing ("writing is hard"). Atwood is a very intelligent writer who makes me feel like an intellectual pipsqueak. she is one of the few current writers I actually admire, so perhaps this is not surprising. Her book explores issues such as "Is a writer a prophet, a high priest, or a court jester?" and "Who are we even writing for?" (ourselves, critics, the masses, etc). Heavy stuff.
Maybe I should stop reading and get writing!
