Zooming out even further than earlier day's photos (possible because I've added more scraps) you can see a bit of the original fabric of the jacket. It's a very unremarkable cotton twill in a very unremarkable brown color of a very unremarkable weight. I've pulled off all the studs and buttons which were an unremarkable Liz Clairborne logo'd brass. The back is getting close to being completely covered with fabric.
