My sister grew up in the United States, where most kids are introduced to arts and crafts at a very young age. As many know, there are two ways to fold a piece of paper: hamburger (narrow edge to narrow edge) or hotdog (wide edge to wide edge).
Allegra: “I was introduced to the folding pattern ‘hot dog versus hamburger style’ in first grade. We were fashioning tri-corner hats out of newspaper. The first step was to fold the newspaper down along a crease to maintain its width, rather than its length. This was referred to as “hamburger style.” If the first step had instead been to fold the newspaper vertically, longer than it was wide, the instruction would have been ‘hot dog style.'”
Me: Did you notice that other teachers referred to hamburger and hotdog folding in class?
Allegra: Oh totally. It was a commonly used instruction in art rooms and day care centers that I went to throughout my childhood. A teacher would say, ‘To make a paper fan, fold the materials hot dog style.’ or ‘To begin your fortune teller, fold the paper hamburger style.’
Analysis: If I could hazard a guess, I think the metaphor works because these sandwich fixings come out of the package with a natural crease. Buns fold along a perforation for easier separation. A hot dog bun opens but does not disintegrate, much like how many paper projects require the traces of former folds to last, so that they may be used later. Two American culinary staples, same dough, two different ways to enjoy them. Hot dogs and hamburgers are also quintessential components to the American child’s diet. Notoriously fussy eaters, the one or two lunch room items every kid likes are hot dogs and hamburgers. Its an easily relatable illustration for a strange new technique, like origami.
