Stealth typewriter/laptop bag
I picked up a beaten Nightmare Before Christmas messenger bag at a rummage sale a couple of years ago, originally intending to use it as a diaper bag (the spousal unit objected, however). But with a few modifications, and pieces removed from an authentic laptop bag, it's now a stealth carrying case for my laptop or a small typewriter. I added the second shoulder strap so I could use the original cinched-up shoulder strap as a handle.
