Im a sentimental person, and when we take vacations I tend to save every simple little thing. I save room keys and matches, tickets and even some casino chips in Vegas. I love making shadow boxes of our vacations. Its more interesting for me to do that than just scrapbook because it gives a place for what would otherwise be clutter in a random cabinet. Working on one from our second trip in Vegas. This was the one I made from the first trip last year.
We are looking to buy a bigger house (preferrably with a basement) and I want a TGIF sort of room where I can hang all our vacation crap on the wall :)
