See my trip posts here (look towards the bottom). What would you have put in the journal?
Some things I put in my journal:
- plane boarding passes
- plane menus
- train tickets
- attraction maps
- attraction tickets
- (cleaned) snack wrappers and lids
- stamps from attractions and train stations
- a (cut up) shopping bag
- owl feather from the owl cafe
- little serving spoons and toothpicks
A tip: if you just tape down one side you can have many things on one page and also space to write about the item beneath it.
