Getting Prepared!

Well.....here I am.....thinking about my trip away this year! I have a new addition thanks to one of the biggies offspring! I have a new suitcase and passport! (but rest assured....I am not a Build-a-Bear bear!) 

However....I have not had a baggage allowance before.....so perhaps I can get some help?

Bearing in mind.....its a small case.....well.....REALLY small.....what could I collect on my travels to take home in my case? 

The case.....is 14cm by 10cm by 3cm......so it's very small! But I wonder what I could collect on my travels?
