I think I showed y'all this, but I wanted to show you the completed case.  A client had me make custom train cases for all her daughters.  I already made and sent a Peter Pan case, and here are the Toy Story and Ratatouille cases.

This one had the original tray and keys!  I'm always scared to lock luggage, though--I'm scared I'll lose the keys while traveling then be stuck without my underwear.  Or whatever.
