Continuing Photoblog Catch-Up Week, here’s another great example of what happens when specialized jargon conflicts with general usage:

Sign requesting donations of 7″×9″ crocheted squares.

It doesn’t take much geometry knowledge to realize you can’t have a 7×9″ square—but in the context of crochet it makes perfect sense. If you take it literally, it’s right up there with non-organic food.
