WIP WED - what the hell is it?

I have an idea

First I painted this

Then began quilting it like this

White ,thread change and a purple marker

Then added this dark thread and may have screwed it up. At this point last night I stopped, needing a fresh start. I may just thread paint the darker so you cant see the under fabric much, or try to make the screw up a shadow somehow? I know this is a wierd one.

And no I did not hijack this vehicle. I am not crazy or drunk (well maybe alittle crazy). You will see when it's done ;-)

Any guesses?

Hint #1. I'm going to cut a hole in the middle and applique onto a dark background.
Hint #2 - think beach
