Bring something real home from your travels. I collect heart shaped stones from all over the world, they grace my window sills, desk and shelves and I can name where I found every one of them. Reef found this one in Tuscany.
Other cool things to collect on your travels :
Sea Glass, Soaps, Coasters (let's face it every country has them!!), Maps (do you know Venice looks like a snapper!), Olive oils, Key rings
They all fit easily in a suitcase and will give you a wonderful memory when you pass them by back home.
