"What!?" you exclaim, doing a spit-take I imagine.
Yes, pretzel necklaces are what I'm talking about. I remember seeing them at my very first beer event and thought it was kinda weird but original of my friends. Once inside, I saw quite a few other people sporting them. It's apparently somewhat common. Hell, the concession stand sold a kit for them. By the way, those kits are terribad. Usually it's a bunch of regular pretzels and a string, but just super overpriced. All assembly required. Might as well make it yourself and get to customize it.
I use shoelaces, as the aglet (that hard end-piece that allows you to lace your shoes) makes threading the pretzels go much quicker. You can pick up a pair of laces for around a buck and then you'll have two necklaces waiting to happen.
The best part of making your own necklace is you get to pick what goes on it. I made a sweet giant pretzel necklace last year. I've seen Funyun necklaces, which I'm planning to do this year. Hell, one guy strung up some bagels, but that seems a bit much to me. If you're willing to possibly stab yourself with a needle, you could thread floss through Cheez-its or peanuts in their shells. Maybe I'll try that next year.
So wear your food. Eat your clothing. Enjoy many small glasses of beer.
And about those tasters: it's hard to keep track of all the beers in the day. I like to take pictures of the labels/signs/whatever for beers I really like. It's too much work for me to pull out a pen and pad of paper after the sixth taster. It's much easier to pull out my phone, snap a picture, and move on.
And if you're going to a beer festival or the like, be sure to wear sunscreen, drink water, and eat definitely before, probably during, and maybe after. Also, cab it or have a DD.
