Why the i-cord is called i-cord
|Quick example of an i-cord
Elizabeth Zimmermann was an British-born knitter that came up with the useful i-cord. Apparently the "i" stands for "idiot" since she thought the technique was so simple anyone could learn it. (from the Knitting Daily).
My significant other wondered about it, since so many things have "i" in the beginning these days, so I looked it up :)
