I came across this gift idea quite awhile ago and have had it tucked away in my brain ever since. For her husband's birthday, Erin Jang of Indigo Bunting bought 24 different kinds of root beer, put them in a vintage soda crate, and made a cheat sheet with the characteristics/tastes of each brand. Brilliant. I think this sort of thing could work with many different items. And it's great for those husbands that are hard to buy for!
