Brother moving to Oz

Hi girls

So my brother is moving to Australia with his girlfriend in a month (I'm really worried as he's only 21!) To work as a tree surgeon which he;s been doing for a few years, great opportunity etc etc.

I wanted to make him a little going away present for him, something small and travel size he can pack in his suitcase- he's renting a furnished apartment so they are literally just taking clothes with them and buying the rest out there.

I dont want it to be something big, or useful. Just a small trinket for his home for him to remember his big sister

I was thinking a small tree shaped door hanger with some embroidered words- does anyone have any nice idea's? I also have some nice photo's of us as kids so might make him up a very small photo album.
